The materialized view partition ttl property has being lost after restarting fe

1. create materialized view
   CREATE MATERIALIZED VIEW mv_hive_order (dt, product_id, gmv)
   PARTITION BY (str2date(dt, '%Y-%m-%d'))
   DISTRIBUTED BY HASH(product_id)
   REFRESH MANUAL
   PROPERTIES (
   "replicated_storage" = "true",
   "partition_refresh_number" = "1",
   "session.enable_spill" = "true",
   "replication_num" = "1",
   "session.query_timeout" = "3600",
   "partition_ttl" = "2 DAY",
   "storage_medium" = "HDD"
   )
   AS SELECT hive_order.dt, hive_order.product_id, sum(hive_order.price) AS gmv
   FROM hive_hms_catalog.ods.hive_order

2. restart fe

3. show create materialized view
   | mv_hive_order | CREATE MATERIALIZED VIEW mv_hive_order (dt, product_id, gmv)
   PARTITION BY (str2date(dt, '%Y-%m-%d'))
   DISTRIBUTED BY HASH(product_id)
   REFRESH MANUAL
   PROPERTIES (
   "replicated_storage" = "true",
   "partition_refresh_number" = "1",
   "session.enable_spill" = "true",
   "replication_num" = "1",
   "session.query_timeout" = "3600",
   "storage_medium" = "HDD"
   )
   AS SELECT hive_order.dt, hive_order.product_id, sum(hive_order.price) AS gmv
   FROM hive_hms_catalog.ods.hive_order
   GROUP BY hive_order.dt, hive_order.product_id;

fix partition ttl lost url : #51194
It was removed when calling the PropertyAnalyzer.analyzePartitionTTL method. Therefore, the properties need to be copied before calling the method and the copied object is used as a parameter. such code :
Map<String, String> props = new HashMap(properties);
Pair<String, PeriodDuration> ttlDuration = PropertyAnalyzer.analyzePartitionTTL(props);

@guanxianchun this is fixed as part of PR #51028
it seems your version does not have the fix.

@guanxianchun this is fixed as part of PR #51028 it seems your version does not have the fix.

I am using the latest code from branch 3.1, which already includes the bug fix code. This is a new issue that arose after using the analyzePartitionTTL method.

It was removed when calling the PropertyAnalyzer.analyzePartitionTTL method:

public static Pair<String, PeriodDuration> analyzePartitionTTL(Map<String, String> properties) {
if (properties != null && properties.containsKey(PROPERTIES_PARTITION_TTL)) {
String ttlStr = properties.get(PROPERTIES_PARTITION_TTL);
PeriodDuration duration;
try {
duration = TimeUtils.parseHumanReadablePeriodOrDuration(ttlStr);
} catch (NumberFormatException e) {
throw new SemanticException(String.format("illegal %s: %s", PROPERTIES_PARTITION_TTL, e.getMessage()));
}
properties.remove(PROPERTIES_PARTITION_TTL);
return Pair.create(ttlStr, duration);
}
return Pair.create(null, PeriodDuration.ZERO);
}

In the analyzePartitionTTL method, the PROPERTIES_PARTITION_TTL property was removed from properties. the code as follow:

properties.remove(PROPERTIES_PARTITION_TTL);
