Wes McKinney updated PARQUET-467:
---------------------------------
Description:
While RLE is the preferred encoding format (and BIT_PACKED is deprecated in
Parquet 2.0), we will need to support this encoding format for legacy Parquet
files that use it. As part of this JIRA we will verify round-tripping levels to
this encoding format.
See also PARQUET-462
was:This is implemented in Impala, but unclear how much data in the wild is
encoded in this format (deprecating according to parquet-format) with RLE as
the preferred encoding (for repetition/definition levels). At minimum we should
raise an exception if this encoding is encoutnered.
> Implement and test BIT_PACKED level encoding / decoding
