> Replace Hadoop ZSTD with JNI-ZSTD
> ---------------------------------
>
> Key: PARQUET-1866
> URL: https://issues.apache.org/jira/browse/PARQUET-1866
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-mr
> Affects Versions: 1.12.0
> Reporter: Xinli Shang
> Assignee: Xinli Shang
> Priority: Major
> Fix For: 1.12.0
>
>
> The parquet-mr repo has been using
> [ZSTD-JNI|https://github.com/luben/zstd-jni/tree/master/src/main/java/com/github/luben/zstd]
> for the parquet-cli project. It is a cleaner approach to use this JNI than
> using Hadoop ZSTD compression, because 1) on the developing box, installing
> Hadoop is cumbersome, 2) Older version of Hadoop doesn't support ZSTD.
> Upgrading Hadoop is another pain. This Jira is to replace Hadoop ZSTD with
> ZSTD-JNI for parquet-hadoop project.
> According to the author of ZSTD-JNI, Flink, Spark, Cassandra all use ZSTD-JNI
> for ZSTD.
> Another approach is to use https://github.com/airlift/aircompressor which is
> a pure Java implementation. But it seems the compression level is not
> adjustable in aircompressor.
