All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog and this project adheres to Semantic Versioning.
'Make all instances writeable' configuration field can be hidden via frontend-core's
set_variable
feature or at runtime.New
get_issues
callback in role API to collect user-defined issues. The issues are gathered from the enabled roles only (present inservice-registry
).Allow disabling built-in HTTP "admin" user:
by specifying
auth_builtin_admin_enabled: false
in theinstances.yml
;using
TARANTOOL_AUTH_BUILTIN_ADMIN_ENABLED=false
environment variable;permanently in
init.lua
:-- init.lua require('cartridge.auth-backend').set_builtin_admin_enabled(false) cartridge.cfg({ auth_backend_name = 'cartridge.auth-backend', ... })
- Make built-in HTTP "admin" user a part of default auth backend. Custom backends are free of it now.
- Eliminate unnecessary transactions after the restart before the replication sync. This reduces the chance the hardware restart leads to WAL corruption (#1546).
- Fix net.box clients compatibility with future tarantool 2.10 versions.
- Fix vshard rebalancer broken by roles reload.
- Compatibility with Tarantool 2.9 (update
errors
dependency to 2.2.1).
New suggestion to restart replication. Whenever the replication isn't running and the reason isn't in the dead upstream, Cartridge will show the corresponding banner in WebUI.
More server details in WebUI: membership, vshard-router, and vshard-storage.
Roles are stopped with the
on_shutdown
trigger where it's supported (in Tarantool 2.8+).New
cartridge.cfg
options:webui_prefix
(default:""
) allows to modify WebUI routes.webui_enforce_root_redirect
(default:true
) manage redirection.
To sum up, now they look as follows:
<PREFIX>/admin/
;<PREFIX>/admin/api
;<PREFIX>/admin/config
;<PREFIX>/admin/cluster/*
;<PREFIX>/static/*
;<PREFIX>/login
;<PREFIX>/logout
;/
and<PREFIX>/
redirect to/<PREFIX>/admin
(if enabled).
New
validate_config
method in GraphQL API.Add
zone
andzone_distances
parameters to test helpers.Support
rebalancer_max_sending
vshard option.
- Merge "Schema" and "Code" pages. Also, allow validating all files, not only
the
schema.yml
. - Allow expelling a leader. Cartridge will appoint a new leader according to the failover priority from the topology.
- Add default
pool.map_call
timeout 10 seconds. - Forbid starting an instance absent in
instances.yml
. - Update
errors
dependency to 2.2.0 with a new methoderrors.netbox_wait_async
to wait fornetbox.future
result. - Update
membership
dependency to 2.4.0 (Changelog). - Update
ddl
dependency to 1.5.0 which supplements the clusterwide config with an example schema (Changelog). - Update
vshard
to 0.1.18 (Changelog).
- Leaders replaced during stateful failover can be expelled now.
- Make failover logging more verbose.
- Fix hot-reload for roles that leave gaps in httpd routes.
- Check user e-mail uniqueness when editing.
- Expelled instances are removed from the
_cluster
space. - Fix
get_enabled_roles
to work without arguments. - Don't default to syslog driver unless
/dev/log
or/var/run/syslog
are available. - Fix inappropriate consistency timeout that led to "Timed out" error during forceful leader promotion.
- Support automatic parsing of Tarantool Enterprise box options
audit_log
andaudit_nonblock
. - Instance won't suspect any members during
RecoveringSnapshot
andBootstrappingBox
.
- Allow to blacklist subpages for complex modules.
- Fix notifications displaying. Close it by clicking anywhere. Keep it open while the mouse is over.
- Various styles enhancements.
- Update vshard to 0.1.17. (Changelog).
- Update graphql to 0.1.1. (Changelog).
- New test helper:
cartridge.test-helpers.stateboard
. - New
failover
option in the cluster test helper for easier failover setup.
- Move DDL related code out of Cartridge and ship it as a permaent role in the
ddl rock. No observable functionality is affected. The roles remains
registered implicitly. Nonetheless it's recomended to add it explicitly to
cartridge.cfg({roles = {'cartridge.roles.ddl-manager'}})
(if it's actually used) as this implicity may be removed in future.
- Fix unclear timeout errors in case of
InitError
andBootError
states. - Fix inconsistency which could occur while longpolling stateboard in unstable networks.
- Increase timeout for the
validate_config
stage from 1 to 10 seconds. It afftectedconfig_patch_clusterwide
in v2.5, mostly on large clusters.
- Highlight if file name exists in file create/rename mode on Code page.
- Extend GraphQL
issues
API withaliens
topic. The issues warns if two separate clusters share the same cluster cookie. - Enhance error messages when they're transferred over network. Supply it with the connection URI.
- Don't skip two-phase commit prematurely. From now on, the decision to skip
the
apply_config
is made by every instance individually. The validation step is never skipped. - Avoid WebUI and
pool.map_call
requests hanging because of network connection problems. - Fix unclear "Timeout exceeded" error. It affects v2.5.0 two-phase commit
when an instance is stuck in
ConfiguringRoles
state. - Make the "Replication isn't running" issue critical instead of a warning.
Issues and suggestions:
- Show an issue when
ConfiguringRoles
state gets stuck for more than 5s. - New GraphQL API:
{ cluster { suggestions { force_apply } } }
to heal the cluster in case of config errors likeConfiguration checksum mismatch
,Configuration is prepared and locked
, and sometimesOperationError
. - New GraphQL API:
{ cluster { suggestions { disable_servers } } }
to restore the quorum in case of some servers go offline.
Configuration options:
- New
cartridge.cfg
optionwebui_enabled
(default:true
). Otherwise, HTTP server remains operable (and GraphQL too), but serves user-defined roles API only. - New
cartridge.cfg
optionhttp_host
(default:0.0.0.0
) which allows to specify the bind address of the HTTP server.
Miscellaneous:
- Allow observing cluster from an unconfigured instance WebUI.
- Introduce a new graphql parser (
libgraphqlparser
instead oflulpeg
). It conforms to the newer GraphQL specification and provides better error messages. The "null" literal is now supported. But some other GraphQL expressions are considered invalid (e.g. empty subselection).
- Properly handle etcd index updates while polling stateful failover updates. The problem affected long-running clusters and resulted in flooding logs with the "Etcd cluster id mismatch" warnings.
- Refactor two-phase commit (
patch_clusterwide
) logics: don't use hardcoded timeout for theprepare
stage, moveupload
to a separate stage. - Eliminate GraphQL error "No value provided for non-null ReplicaStatus" when
a replica is removed from the
box.space._cluster
. - Allow specifying server zone in
join_server
API. - Don't make formatting ugly during config upload.
- Allow disabling instances and fix their style.
- Show a suggestion to disable broken instances.
- Show a suggestion to force reapply clusterwide configuration.
- Hide the bootstrap button when it's not necessary (e.g. before the cluster is bootstrapped, and in vshardless cluster too).
- Properly display an error if changing server zone fails.
Zones and zone distances:
- Add support of replica weights and zones via a clusterwide config new section
zone_distances
and a server parameterzone
.
Fencing:
- Implement a fencing feature. It protects a replicaset from the presence of multiple leaders when the network is partitioned and forces the leader to become read-only.
- New failover parameter
failover_timout
specifies the time (in seconds) used by membership to marksuspect
members asdead
which triggers failover. - Fencing parameters
fencing_enabled
,fencing_pause
,fencing_timeout
are available for customization via Lua and GraphQL API, and in WebUI too.
Issues and suggestions:
New GraphQL API:
{ cluster { suggestions { refine_uri } } }
to heal the cluster after relocation of serversadvertise_uri
.New Lua API
cartridge.config_force_reapply()
and similar GraphQL mutationcluster { config_force_reapply() }
to heal several operational errors:- "Prepare2pcError: Two-phase commit is locked";
- "SaveConfigError: .../config.prepare: Directory not empty";
- "Configuration is prepared and locked on ..." (an issue);
- "Configuration checksum mismatch on ..." (an issue).
It'll unlock two-phase commit (remove
config.prepare
lock), upload the active config from the current instance and reconfigure all roles.
Hot-reload:
- New feature for hot reloading roles code without restarting an instance --
cartridge.reload_roles
. The feature is experimental and should be enabled explicitly:cartridge.cfg({roles_reload_allowed = true})
.
Miscellaneous:
- New
cartridge.cfg
optionswim_broadcast
to manage instances auto-discovery on start. Default: true. - New argparse options support for tarantool 2.5+:
replication_synchro_quorum
,replication_synchro_timeout
,memtx_use_mvcc_engine
.
- Default value of
failover_timeout
increased from 3 to 20 seconds (important change). - RPC functions now consider
suspect
members as healthy to be in agreement with failover (important change).
- Don't stuck in
ConnectingFullmesh
state when instance is restarted with a differentadvertise_uri
. Also keep "Server details" dialog in WebUI operable in this case. - Allow applying config when instance is in
OperationError
. It doesn't cause loss of quorum anymore. - Stop vshard fibers when the corresponding role is disabled.
- Make
console.listen
error more clear whenconsole_sock
exceedsUNIX_PATH_MAX
limit. - Fix
upstream.idle
issue tolerance to avoid unnecessary warnings "Replication: long idle (1 > 1)". - Allow removing spaces from DDL schema for the sake of
drop
migrations. - Make DDL schema validation stricter. Forbid redundant keys in schema top-level
and make
spaces
mandatory.
- Update server details modal, add support for server zones.
- Properly display errors on WebUI pages "Users" and "Code".
- Indicate config checksum mismatch in issues list.
- Indicate the change of
arvertise_uri
in issues list. - Show an issue if the clusterwide config is locked on an instance.
- Refresh interval and stat refresh period variables can be customized via
frontend-core's
set_variable
feature or at runtime.
- When failover mode is stateful, all manual leader promotions will be consistent:
every instance before becoming writable performs
wait_lsn
operation to sync with previous one. If consistency couldn't be reached due to replication failure, a user could either revert it (promote previous leader), or force promotion to be inconsistent. - Early logger initialization (for Tarantool > 2.5.0-100, which supports it).
- Add
probe_uri_timeout
argparse option responsible for retrying "Can't ping myself" error on startup. - New test helper:
cartridge.test-helpers.etcd
. - Support
on_push
andon_push_ctx
options forcartridge.rpc_call()
. - Changing users password invalidates HTTP cookie.
- Support GraphQL default variables.
- Eventual failover may miss an event while roles are being reconfigured.
- Compatibility with pipe logging, see tarantool/tarantool#5220.
- Non-informative assertion when instance is bootstrapped with a distinct
advertise_uri
. - Indexing
nil
value inget_topology()
query. - Initialization race of vshard storage which results in
OperationError
. - Lack of vshard router attempts to reconnect to the replicas.
- Make GraphQL syntax errors more clear.
- Better
errors.pcall()
performance,errors
rock updated to v2.1.4.
- Show instance names in issues list.
- Show app name in window title.
- Add the "Force leader promotion" button in the stateful failover mode.
- Indicate consistent switchover problems with a yellow leader flag.
- When running under systemd use
<APP_NAME>.<INSTANCE_NAME>
as default syslog identity. - Support
etcd
as state provider for stateful failover.
- Improve rocks detection for feedback daemon. Besides cartridge version it
now parses manifest file from the
.rocks/
directory and collects rocks versions. - Make
uuid
parameters optional for test helpers. Makeservers
option accept number of servers in replicaset.
- Prettier errors displaying.
- Enhance replicaset filtering by role / status.
- Error stacktrace received from the backend is shown in notifications.
- Avoid trimming
console_sock
if it's name is too long. - Fix file descriptors leak during box recovery.
- Support
console_sock
option in stateboard as well as notify socket and other box options similar to regular cartridge instances.
- Frontend core update: fix route mapping
- Implement stateful failover mode. You can read more in ":ref:`Failover architecture <cartridge-failover>`" documentation topic.
- Respect
box.cfg
optionswal_dir
,memtx_dir
,vinyl_dir
. They can be either absolute or relative - in the later case it's calculated relative tocartridge.workdir
. - New option in
cartridge.cfg({upgrade_schema=...})
to automatically upgrade schema to modern tarantool version (only for leader). It also has been added forargparse
. - Extend GraphQL
issues
API with various topics:replication
,failover
,memory
,clock
. Make thresholds configurable via argparse.
- Make GraphQL validation stricter: scalar values can't have sub-selections; composite types must have sub-selections; omitting non-nullable arguments in variable list is forbidden. Your code may be affected if it doesn't conform GraphQL specification.
- GraphQL query
auth_params
returns "fullname" (if it was specified) instead of "username". - Update
errors
dependency to 2.1.3. - Update
ddl
dependency to 1.1.0.
Lua API:
cartridge.admin_get_failover
->cartridge.failover_get_params
cartridge.admin_enable/disable_failover
->cartridge.failover_set_params
GraphQL API:
query {cluster {failover} }
->query {cluster {failover_params {...} } }
mutation {cluster {failover()} }
->mutation {cluster {failover_params() {...} } }
Properly handle nested input object in GraphQL:
mutation($uuid: String!) { cluster { edit_topology(servers: [{uuid: $uuid ...}]) {} } }
Show WebUI notification on successful config upload.
Repair GraphQL queries
add_user
,issues
on uninitialized instance.
- Show "You are here" marker.
- Show application and instance names in app title.
- Indicate replication and failover issues.
- Fix bug with multiple menu items selected.
- Refactor pages filtering, forbid opening blacklisted pages.
- Enable JS chunks caching.
- Expose membership options in
argparse
module (edit them with environment variables and command-line arguments). - New internal module to handle
.tar
files.
Lua API:
cartridge.cfg({webui_blacklist = {'/admin/code', ...}})
: blacklist certain WebUI pages.cartridge.get_schema()
referencing older_G.cartridge_get_schema
.cartridge.set_schema()
referencing older_G.cartridge_set_schema
.
GraphQL API:
- Make use of GraphQL error extensions: provide additional information
about
class_name
andstack
of original error. cluster{ issues{ level message ... }}
: obtain more details on replication statuscluster{ self {...} }
: new fieldsapp_name
,instance_name
.servers{ boxinfo { cartridge {...} }}
: new fieldsversion
,state
,error
.
Test helpers:
- Allow specifying
all_rw
replicaset flag in luatest helpers. - Add
cluster({env = ...})
option for specifying clusterwide environment variables.
- Remove redundant topology availability checks from two-phase commit.
- Prevent instance state transition from
ConnectingFullmesh
toOperationError
if replication fails to connect or to sync. Since now such fails result in staying inConnectingFullmesh
state until it succeeds. - Specifying
pool.connect()
optionsuser
,password
,reconnect_after
are deprecated and ignored, they never worked as intended and will never do. Optionconnect_timeout
is deprecated, but for backward compatibility treated aswait_connected
.
- Fix DDL failure if
spaces
field isnull
in input schema. - Check content of
cluster_cookie
for absence of special characters so it doesn't break the authorization. Allowed symbols are[a-zA-Z0-9_.~-]
. - Drop remote-control connections after full-featured
box.cfg
becomes available to prevent clients from using limited functionality for too long. During instance recovery remote-control won't accept any connections: clients wait for box.cfg to finish recovery. - Update errors rock dependency to 2.1.2: eliminate duplicate stack
trace from
error.str
field. - Apply
custom_proc_title
setting without waiting forbox.cfg
. - Make GraphQL compatible with
req:read_cached()
call in httpd hooks. - Avoid "attempt to index nil value" error when using rpc on an uninitialized instance.
- Add an ability to hide certain WebUI pages.
- Validate YAML in code editor WebUI.
- Fix showing errors in Code editor page.
- Remember last open file in Code editor page. Open first file when local storage is empty.
- Expand file tree in Code editor page by default.
- Show Cartridge version in server info dialog.
- Server alias is clickable in replicaset list.
- Show networking errors in splash panel instead of notifications.
- Accept float values for vshard-storage weight.
- Expose
TARANTOOL_DEMO_URI
environment variable in GraphQL querycluster{ self{demo_uri} }
for demo purposes.
- Notifications in schema editor WebUI.
- Fix GraphQL
servers
query compatibility with old cartridge versions. - Two-phase commit backward compatibility with v1.2.0.
- Use for frontend part single point of configuration HTTP handlers. As example: you can add your own client HTTP middleware for auth.
- Built-in DDL schema management. Schema is a part of clusterwide configuration. It's applied to every instance in cluster.
- DDL schema editor and code editor pages in WebUI.
- Instances now have internal state machine which helps to manage cluster operation and protect from invalid state transitions.
- WebUI checkbox to specify
all_rw
replicaset property. - GraphQL API for clusterwide configuration management.
- Measure clock difference across instances and provide
clock_delta
in GraphQLservers
query and inadmin.get_servers()
Lua API. - New option in
rpc_call(..., {uri=...})
to perform a call on a particular uri.
cartridge.rpc_get_candidates()
doesn't return error "No remotes with role available" anymore, empty table is returned instead. (incompatible change)- Base advertise port in luatest helpers changed from 33000 to 13300,
which is outside
ip_local_port_range
. Using port from local range usually caused tests failing with an error "address already in use". (incompatible change, but affects tests only) - Whole new way to bootstrap instances. Instead of polling membership for getting clusterwide config the instance now start Remote Control Server (with limited iproto protocol functionality) on the same port. Two-phase commit is then executed over net.box connection. (major change, but still compatible)
- Failover isn't triggered on
suspect
instance state anymore - Functions
admin.get_servers
,get_replicasets
and similar GraphQL queries now return an error if the instance handling the request is in stateInitError
orBootError
. - Clusterwide configuration is now represented with a file tree.
All sections that were tables are saved to separate
.yml
files. Compatibility with the old-style configuration is preserved. Accessing unmarshalled sections withget_readonly/deepcopy
methods is provided without.yml
extension as earlier. (major change, but still compatible) - After an old leader restarts it'll try to sync with an active one
before taking the leadership again so that failover doesn't switch too
early before leader finishes recovery. If replication setup fails the
instance enters the
OperationError
state, which can be avoided by explicitly specifyingreplication_connect_quorum = 1
(or 0). (major change) - Option
{prefer_local = false}
inrpc_call
makes it always use netbox connection, even to connect self. It never tries to perform call locally. - Update
vshard
dependency to 0.1.14.
- Function
cartridge.bootstrap
is removed. Useadmin_edit_topology
interad. (incompatible change) - Misspelled role callback
validate
is now removed completely. Keep usingvalidate_config
.
- Arrange proper failover triggering: don't miss events, don't trigger
if nothing changed. Fix races in calling
apply_config
between failover and two-phase commit. - Race condition when creating working directory.
- Hide users page in WebUI when auth backend implements no user management functions. Enable auth switcher is displayed on main cluster page in this case.
- Displaying boolean values in server details.
- Add deduplication for WebUI notifications: no more spam.
- Automatically choose default vshard group in create and edit replicaset modals.
- Enhance WebUI modals scrolling.
- 'Auto' placeholder to weight input in the Replicaset forms.
- 'Select all' and 'Deselect all' buttons to roles field in Replicaset add and edit forms.
- Refresh replicaset list in UI after topology edit actions: bootstrap, join, expel, probe, replicaset edit.
- New Lua API
cartridge.http_authorize_request()
suitable for checking HTTP request headers. - New Lua API
cartridge.http_render_response()
for generating HTTP response with properSet-Cookie
headers. - New Lua API
cartridge.http_get_username()
to check authorization of active HTTP session. - New Lua API
cartridge.rpc_get_candidates()
to get list of instances suitable for performing a remote call. - Network error notification in UI.
- Allow specifying vshard storage group in test helpers.
- Get UI components from Tarantool UI-Kit
- When recovering from snapshot, instances are started read-only. It is still possible to override it by argparse (command line arguments or environment variables)
- Editing topology with
failover_priority
argument. - Now
cartridge.rpc.get_candidates()
returns value as specified in doc. Also it accepts new optionhealthy_only
to filter instances which have membership status healthy. - Replicaset weight tooltip in replicasets list
- Total buckets count in buckets tooltip
- Validation error in user edit form
- Leader flag in server details modal
- Human-readable error for invalid GrqphQL queries:
Field "x" is not defined on type "String"
- User management error "attempt to index nil value" when one of users has empty e-mail value
- Catch
rpc_call
errors when they are performed locally
- New Lua API
admin_edit_topology
has been added to unite multiple others:admin_edit_replicaset
,admin_edit_server
,admin_join_server
,admin_expel_server
. It's suitable for editing multiple servers/replicasets at once. It can be used for bootstrapping cluster from scratch, joining a server to an existing replicaset, creating new replicaset with one or more servers, editing uri/labels of servers, disabling or expelling servers. - Similar API is implemented in a GraphQL mutation
cluster{edit_topology()}
. - New GraphQL mutation
cluster { edit_vshard_options }
is suitable for fine-tuning vshard options:rebalancer_max_receiving
,collect_lua_garbage
,sync_timeout
,collect_bucket_garbage_interval
,rebalancer_disbalance_threshold
.
- Both bootstrapping from scratch and patching topology in clusterwide config automatically probe servers, which aren't added to membership yet (earlier it influenced join_server mutation only). This is a prerequisite for multijoin api implementation.
- WebUI users page is hidden if auth_backend doesn't provide list_users callback.
Lua API:
cartridge.admin_edit_replicaset()
cartridge.admin_edit_server()
cartridge.admin_join_server()
cartridge.admin_expel_server()
GraphQL API:
mutation{ edit_replicaset() }
mutation{ edit_server() }
mutation{ join_server() }
mutation{ expel_server() }
- Protect
users_acl
andauth
sections when downloading clusterwide config. Also forbid uploading them.
- New parameter
topology.replicasets[].all_rw
in clusterwide config for configuring all instances in the replicaset asread_only = false
. It can be managed with both GraphQL and Lua APIedit_replicaset
. - Remote Control server - a replacement for the
box.cfg({listen})
, with limited functionality, independent onbox.cfg
. The server is only to be used internally for bootstrapping new instances. - New module
argparse
for gathering configuration options from command-line arguments, environment variables, and configuration files. It is used internally and overridescluster.cfg
andbox.cfg
options. - Auth parameter
cookie_max_age
is now configurable with GraphQL API. Also now it's stored in clusterwide config, so changing it on a single server will affect all others in cluster. - Detect that we run under systemd and switch to syslog logging from
stderr. This allows to filter log messages by severity with
journalctl
- Redesign WebUI
- The project renamed to cartridge.
Use
require('cartridge')
instead ofrequire('cluster')
. All submodules are renamed too. (incompatible change) - Submodule
cluster.test_helpers
renamed tocartridge.test-helpers
for consistency. (incompatible change) - Modifying auth params with GraphQL before the cluster was bootstrapped is now forbidden and returns an error.
- Introducing a new auth parameter
cookie_renew_age
. When cluster handles an HTTP request with the cookie, whose age in older then specified, it refreshes the cookie. It may be useful to setcookie_max_age
to a small value (for example 10 minutes), so the user will be logged out aftercookie_max_age
seconds of inactivity. Otherwise, if he's active, the cookie will be updated everycookie_renew_age
seconds and the session will not be interrupted. - Changed configuration options for
cluster.cfg()
:roles
now is a mandatory table,workdir
is optional now (defaults to ".") - Parameter
advertise_uri
is optional now, default value is derived as follows.advertise_uri
is a compound of<HOST>
and<PORT>
. When<HOST>
isn't specified, it's detected as the only non-local IP address. If it can't be determined or there is more than one IP address available it defaults to"localhost"
. When<PORT>
isn't specified, it's derived from numeric suffix_<N>
ofTARANTOOL_INSTANCE_NAME
:<PORT> = 3300+<N>
. Otherwise default<PORT> = 3301
is used. - Parameter
http_port
is derived from instance name too. If it can't be derived it defaults to 8081. New parameterhttp_enabled = false
is used to disable it (by default it's enabled). - Removed user
cluster
, which was used internally for orchestration over netbox. Tarantool built-in useradmin
is used instead now. It can also be used for HTTP authentication to access WebUI. Cluster cookie is used as a password in both cases. (incompatible change)
Two-layer table structure in API, which was deprecated earlier, is now removed completely:
cartridge.service_registry.*
cartridge.confapplier.*
cartridge.admin.*
Instead you can use top-level functions:
cartridge.config_get_readonly
cartridge.config_get_deepcopy
cartridge.config_patch_clusterwide
cartridge.service_get
cartridge.admin_get_servers
cartridge.admin_get_replicasets
cartridge.admin_probe_server
cartridge.admin_join_server
cartridge.admin_edit_server
cartridge.admin_expel_server
cartridge.admin_enable_servers
cartridge.admin_disable_servers
cartridge.admin_edit_replicaset
cartridge.admin_get_failover
cartridge.admin_enable_failover
cartridge.admin_disable_failover
- Cluster can now operate without vshard roles (if you don't need sharding).
Deprecation warning about implicit vshard roles isn't issued any more,
they aren't registered unless explicitly specified either in
cluster.cfg({roles=...})
or independencies
to one of user-defined roles. - New role flag
hidden = true
. Hidden roles aren't listed incluster.admin.get_replicasets().roles
and therefore in WebUI. Hidden roles are supposed to be a dependency for another role, yet they still can be enabled withedit_replicaset
function (both Lua and GraphQL). - New role flag:
permanent = true
. Permanent roles are always enabled. Also they are hidden implicitly. - New functions in cluster test_helpers -
Cluster:upload_config(config)
andCluster:download_config()
cluster.call_rpc
used to return 'Role unavailable' error as a first argument instead ofnil, err
. It can appear when role is specified in clusterwide config, but wasn't initialized properly. There are two reasons for that: race condition, or prior error in either roleinit
orapply_config
methods.
- Update frontend-core dependency which used to litter
package.loaded
with tons of JS code
- Support for vshard groups in WebUI
- Uniform handling vshard group 'default' when multiple groups aren't configured
- Requesting multiple vshard groups info before the cluster was bootstrapped
- User management page in WebUI
- Configuring multiple isolated vshard groups in a single cluster
- Support for joining multiple instances in a single call to config_patch_clusterwide
- Integration tests helpers
- GraphQL API
known_roles
format now includes roles dependencies cluster.rpc_call
optionremote_only
renamed toprefer_local
with the opposite meaning
- Don't display renamed or removed roles in webui
- Uploading config without a section removes it from clusterwide config
- Specifying role dependencies
- Set read-only option for slave nodes
- Labels for servers
- Admin http endpoint changed from /graphql to /admin/api
- Graphql output now contains null values for empty objects
- Deprecate implicity of vshard roles
'cluster.roles.vshard-storage'
,'cluster.roles.vshard-router'
. Now they should be specified explicitly incluster.cfg({roles = ...})
cluster.service_get('vshard-router')
now returnscluster.roles.vshard-router
module instead ofvshard.router
(incompatible change)cluster.service_get('vshard-storage')
now returnscluster.roles.vshard-storage
module instead of vshard.storage` (incompatible change)cluster.admin.bootstrap_vshard
now can be called on any instance
- Operating vshard-storage roles before vshard was bootstrapped
- Failover priority configuration using WebUI
- Remote calls across cluster instances using
cluster.rpc
module - Displaying
box.cfg
andbox.info
in WebUI - Authorization for HTTP API and WebUI
- Configuration download/upload via WebUI
- Lua API documentation, which you can read with
tarantoolctl rocks doc cluster
command.
- Instance restart now triggers config validation before roles initialization
- Update WebUI design
- Lua API changed (old functions still work, but issue warnings):
-
cluster.confapplier.*
->cluster.config_*
-cluster.service_registry.*
->cluster.service_*
- Cluster used to call 'validate()' role method instead of documented 'validate_config()', so it was added. The undocumented 'validate()' still may be used for the sake of compatibility, but issues a warning that it was deprecated.
- Minor internal corner cases
- UI/UX: Replace "bootstrap vshard" button with a noticable panel
- UI/UX: Replace failover panel with a small button
- Ability to disable vshard-storage role when zero-weight rebalancing finishes
- Active master indication during failover
- Other minor improvements
- New frontend core
- Dependencies update
- Call to
join_server
automatically doesprobe_server
- Servers filtering by roles, uri, alias in WebUI
- WebUI errors
- Graphql mutations order
- Callbacks in user-defined roles are called with
is_master
parameter, indicating state of the instance - Combine
cluster.init
andcluster.register_role
api calls in singlecluster.cfg
- Eliminate raising exceptions
- Absorb http server in
cluster.cfg
- Support of vshard replicaset weight parameter
join_server()
timeout
parameter to make call synchronous
- Uncaught exception in WebUI
- Indicate when backend is unavailable
- Sort servers in replicaset, put master first
- Cluster mutations are now synchronous, except joining new servers
- Lua API for temporarily disabling servers
- Lua API for implementing user-defined roles
- Config structure incompatible with v0.2
- Explicit vshard master configuration
- Automatic failover (switchable)
- Unit tests
- Allow vshard bootstrapping from ui
- Several stability improvements
- Basic functionality
- Integration tests
- Luarock-based packaging
- Gitlab CI integration
