-------------------------------
Summary: [Python] Expose Parquet ZSTD compression (was: Missing pyarrow
ZSTD support for Parquet)
> [Python] Expose Parquet ZSTD compression
> ----------------------------------------
>
> Key: ARROW-2677
> URL: https://issues.apache.org/jira/browse/ARROW-2677
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Affects Versions: 0.9.0
> Reporter: William Lee
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> It seems like in the python/pyarrow/_parquet.pyx file there's a check for the
> supported compression scheme:
> {code}
> cdef int check_compression_name(name) except -1:
> if name.upper() not in ['NONE', 'SNAPPY', 'GZIP', 'LZO', 'BROTLI', 'LZ4']:
> raise ArrowException("Unsupported compression: " + name)
> return 0{code}
> which does not include ZSTD (Zstandard). From my understanding it should be
> supported in the underlying c++ library already. Is it possible to add that
> support?
