[jira] [Commented] (SPARK-19112) add codec for ZStandard

    [ https://issues.apache.org/jira/browse/SPARK-19112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15999363#comment-15999363 ] 

Sean Owen commented on SPARK-19112:
-----------------------------------

The benchmark suggests this is significantly slower than lz4 though; probably not worth building into Spark?

> ZStandard: https://github.com/facebook/zstd and http://facebook.github.io/zstd/ has been in use for a while now. v1.0 was recently released. Hadoop (https://issues.apache.org/jira/browse/HADOOP-13578) and others (https://issues.apache.org/jira/browse/KAFKA-4514) are adopting it.
> Zstd seems to give great results => Gzip level Compression with Lz4 level CPU.
