What's changed and what's your intention?

This PR introduces index options to the metric engine, addressing scenarios with high cardinality where inverted index files can grow excessively large. By allowing users to specify index types and parameters, such as skipping indexes with customizable granularity, users can better control index behavior and optimize storage.

For example:
In this case, all auto-added columns will apply the index options specified by the user.

CREATE TABLE phy (
    ts TIMESTAMP TIME INDEX, 
    val DOUBLE
) ENGINE=metric WITH (
    "physical_metric_table" = "", 
    "index.type" = "skipping", 
    "index.granularity" = "8192"
);

If a logical table is created on the physical table:

CREATE TABLE t1 (
    ts TIMESTAMP TIME INDEX, 
    val DOUBLE, 
    host STRING PRIMARY KEY
) ENGINE=metric WITH (
    "on_physical_table" = "phy"
);

The resulting physical table will have the following schema:

+-------+---------------------------------------------------------------------------------+
| Table | Create Table                                                                    |
+-------+---------------------------------------------------------------------------------+
| phy   | CREATE TABLE IF NOT EXISTS "phy" (                                              |
|       |   "ts" TIMESTAMP(3) NOT NULL,                                                   |
|       |   "val" DOUBLE NULL,                                                            |
|       |   "host" STRING NULL SKIPPING INDEX WITH(granularity = '8192', type = 'BLOOM'), |
|       |   TIME INDEX ("ts"),                                                            |
|       |   PRIMARY KEY ("host"),                                                         |
|       | )                                                                               |
|       |                                                                                 |
|       | ENGINE=metric                                                                   |
|       | WITH(                                                                           |
|       |   'index.granularity' = '8192',                                                 |
|       |   'index.type' = 'skipping',                                                    |
|       |   physical_metric_table = ''                                                    |
|       | )                                                                               |

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
