[ASTERIXDB-3129][STO][RT] Add columnn encoders/decoders
- user mode changes: no
- storage format changes: no
- interface changes: yes
Details:
- Add a modified version of Parquet's encoders/decoders
that fits our needs and avoids object creation. Also,
accepts Hyracks values (i.e., IValueReference)
- Add column streams (in/out) for reading/writing
encoded column values
Interface changes:
Add close() to the interface for IColumnTupleIterator
to log the number of filtered pages.
