Ethan Guo updated HUDI-3532:
----------------------------
Description:
The api {{getColumnStats}} is not supported in FileSystemBackedTableMetadata:
{code:java}
@Override
public Map<Pair<String, String>, HoodieMetadataColumnStats>
getColumnStats(final List<Pair<String, String>> partitionNameFileNameList,
final String columnName)
throws HoodieMetadataException {
throw new HoodieMetadataException("Unsupported operation:
getColumnsStats!");
} {code}
It's better to support column stats without metadata table from
FileSystemBackedTableMetadata as well to unify the logic around col stats and
reduce the special-cased logic for col stats between metadata table vs file
system backed metadata.
> Refactor FileSystemBackedTableMetadata and related classes to support
> getColumnStats directly
