Antoine Pitrou resolved PARQUET-1241.
-------------------------------------
Fix Version/s: (was: cpp-4.0.0)
Resolution: Won't Do
We're abandoning this. Instead, PARQUET-1996 added a definition for new LZ4_RAW
compression format which uses the LZ4 "block" codec without Hadoop-specific
framing.
The C++ implementation of LZ4_RAW is tracked by PARQUET-1998.
> [C++] Use LZ4 frame format
> --------------------------
>
> Key: PARQUET-1241
> URL: https://issues.apache.org/jira/browse/PARQUET-1241
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-cpp, parquet-format
> Reporter: Lawrence Chan
> Priority: Major
>
> The parquet-format spec doesn't currently specify whether lz4-compressed data
> should be framed or not. We should choose one and make it explicit in the
> spec, as they are not inter-operable. After some discussions with others [1],
> we think it would be beneficial to use the framed format, which adds a small
> header in exchange for more self-contained decompression as well as a richer
> feature set (checksums, parallel decompression, etc).
> The current arrow implementation compresses using the lz4 block format, and
> this would need to be updated when we add the spec clarification.
> If backwards compatibility is a concern, I would suggest adding an additional
> LZ4_FRAMED compression type, but that may be more noise than anything.
