>             Project: Apache Hudi
>          Issue Type: Improvement
>          Components: code-quality, writer-core
>            Reporter: Ethan Guo
>            Priority: Minor
>             Fix For: 0.12.1

> 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.
