[jira] [Created] (BIGTOP-3921) Add ZSTD Codec Support for hadoop

Robin Zuo created BIGTOP-3921:
---------------------------------

             Summary: Add ZSTD Codec Support for hadoop
                 Key: BIGTOP-3921
                 URL: https://issues.apache.org/jira/browse/BIGTOP-3921
             Project: Bigtop
          Issue Type: Improvement
            Reporter: Robin Zuo


{*}Zstandard{*}, or {{zstd}} as short version, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by [Huff0 and FSE library|https://github.com/Cyan4973/FiniteStateEntropy].

 

ZSTD is famous for its better than other codecs.

When maintaining the same compression ratio, the decompression and compression rates are much higher than snappy; When maintaining the same decompression and compression rates, the compression ratio is about 50% higher than snappy.

 

For more detailed performance test result, please refer to zstd github repository:

So, I'd like add ZSTD codec compiled to hadoop native library by default.
