Alexey Kudinkin commented on HUDI-2928:
---------------------------------------
Unfortunately we won't be able to support Zstd w/o herculean effort of hacking
around Parquet implementation as it's not unfortunately modularized well-enough
to support outside extensions.
The only sensible way at this point seem to be waiting for Spark/Parquet
upgrade to 1.12.

> Currently, having Gzip as a default we prioritize Compression/Storage cost at
> the expense of
> * Compute (on the {+}write-path{+}): about *30%* of Compute burned during
> bulk-insert in local benchmarks on Amazon Reviews dataset is Gzip (see below)
> * Compute (on the {+}read-path{+}), as well as queries Latencies: queries
> scanning large datasets are likely to be compression-/CPU-bound (Gzip t/put
> is *3-4x* less than Snappy, Zstd,
> [EX|https://stackoverflow.com/a/56410326/3520840])
> P.S Spark switched its default compression algorithm to Snappy [a while
> ago|https://github.com/apache/spark/pull/12256].

> *EDIT*
> We should actually evaluate putting in

> instead of Snappy. It has compression ratios comparable to Gzip, while
> bringing in much better performance:
