## Proposed changes Relevant pr #23391 #21873 Now `FE` does not record the last update time of hms tbl's partitons, so the sql cache may be hit even the hive table's partitions have changed. This pr add a field to record the last partition update time, and use it when enable sql-cache. The cache will be missed if some partitions have changed at hive side. Use `System.currentTimeMillis()` but not the event time of hms event because we would better keep the same measurement with the `lastUpdateTime` of hms table. Add this value to `ExternalObjectLog` because it is better to keep the same time with all `FE`s, so the sql-cache can be hit by the querys through the different `FE`s. ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
