Jingsong Lee created FLINK-18508: ------------------------------------ Summary: Dynamic source supports statistics and parallelism report Key: FLINK-18508 URL: https://issues.apache.org/jira/browse/FLINK-18508 Project: Flink Issue Type: New Feature Components: Table SQL / API Reporter: Jingsong Lee Fix For: 1.12.0
Add SupportsStatisticsReport and SupportsParallelismReport to dynamic source, source can return some information to help table optimizer. This information can be more accurate from the source rather than the catalog. For example, for iceberg / filesystem connector, after filter and partition pushdown, the statistics have been greatly adjusted, and many files may have been filtered out. -- This message was sent by Atlassian Jira (v8.3.4#803005)
