@KnightChess by default, incremental meta sync is enabled (`hoodie.meta.sync.incremental=true`), which means that the table partitions since the last time the table is synced are fetched first from the table (see [`HiveSyncTool#syncHoodieTable`](https://github.com/apache/hudi/blob/release-0.14.0/hudi-sync/hudi-hive-sync/src/main/java/org/apache/hudi/hive/HiveSyncTool.java#L282)). When `hoodie.datasource.hive_sync.filter_pushdown_enabled` is true, Hive sync uses the list of table partitions changed for filter push down. If the list of changed partitions is too large, the filter pushdown may not be effective. You may give it a try and see if there is benefit in your case. -- This is an automated message from the Apache Git Service.
