Vinaykumar Bhat commented on HUDI-7007:
---------------------------------------
Seems like `
FunctionalIndexSupport::loadFunctionalIndexDataFrame(...)` is always called
(from `HoodieFileIndex::lookupCandidateFilesInMetadataTable(...)` with an empty
`indexPartition` string. So, it is likely that file pruning based on functional
index is not supported.

> Currently, one can create a functional index on a column using bloom filters.
> However, only the one created using column stats is supported on the reader
> side (check `FunctionalIndexSupport`). This ticket tracks the support for
> using bloom filters on functional index in the reader path.
