[jira] [Commented] (HADOOP-16244) Hadoop Support ISA-L
Compress/Decompress

------------------------------------------
Thanks for bring it up. I am not aware of ISA-L compress/decompress library. As for high performance compression library, ZSTD seems quite promising these days.

> In hadoop 3.0.0+ , for default RS codec, there is also a native implementation which leverages Intel ISA-L library to improve the performance of codec. as we know, ISA-L has set of highly optimized functions include compression/decompression base on gzip. can ISA-L compatible with hadoop to provide highly performance of un/compress? however, hadoop comunity seem not support isa-l compression & decompression up to now. Has some problem in ISA-L compress-support?
> Can someone share the experience in this area? thanks a lot!
