Xinli Shang updated PARQUET-1866:
---------------------------------
Description:
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.
