### Change Logs - Enabling cols stats by default on writer in SPARK engine - Added support for timestamp, Date, LocalDate, Decimal. Few features/tests where col stats is disabled: - Bootstrap feature is not yet supported. We need to fix it for whole of metadata table. https://issues.apache.org/jira/browse/HUDI-8774 - Schema evolution w/ partition stats is not yet tackled in this patch. https://issues.apache.org/jira/browse/HUDI-8587 - Some tests w/ test table infra does not support. Bcoz, whole premise w/ test table infra is to just mock the functionality w/ empty files. And so both col stats and partition stats are not supported. - https://issues.apache.org/jira/browse/HUDI-8774 (more complex data types) - https://issues.apache.org/jira/browse/HUDI-8814 Enabling col stats and partition stats by default in flink and java. ### Impact Enabling col stats by default on the writer will improve query performance. ### Risk level (write none, low medium or high below) medium ### Documentation Update _Describe any necessary documentation update if there is any new feature, config, or user-facing change.
