lsyldliu opened a new pull request, #21556:
URL: https://github.com/apache/flink/pull/21556
## What is the purpose of the change
Hive table partition supports deserializing later during runtime, the
JobManager needs to deserialize it for the enumerator, but the partition info
isn't required for TaskManager, so we don't need to deserialize it, so we can
reduce the cost of the task initializing phase.
