> Key: HUDI-4396
> URL: https://issues.apache.org/jira/browse/HUDI-4396
> Project: Apache Hudi
> Issue Type: Improvement
> Reporter: XixiHua
> Priority: Major
>
> Currently, when using the HudiHiveSync and DataHubSyncTool tools to do hive table columns changes, this happens at HMSDDLExecutor.updateTableDefinition(), this cascade is only decided by META_SYNC_PARTITION_FIELDS:
> {code:java}
> boolean cascade = syncConfig.getSplitStrings(META_SYNC_PARTITION_FIELDS).size() > 0;{code}
> but some scenarios do not need to update partition columns but this will cost a lot of time even the hive might hang when the partition number is large.
> Therefore, I want to add a supplement boolean config parameter:
> *PARTITION_CASCADE_WITH_COLUMN_CHANGE*
> the default is true, if the users don't want to update the partition then set it to false
