Changes

Here are important changes in this release:

  • Supported column value compression with Zstandard
  • Changed to stop compressing small data

Supported column value compression with Zstandard

In this release, additional compression algorithm is supported - Zstandard.

Then, you can use it by adding COMPRESS_ZSTD flag to column_create:

column_create Memos content COLUMN_SCALAR|COMPRESS_ZSTD Text

Above command creates content column in Memo table which supports column value compression with Zstandard.

Changed to stop compressing small data

If column data is less than 256 byte, the data aren't compressed even when COMPRESS_ZLIB or COMPRESS_LZ4 or COMPRESS_ZSTD is specified.

It's for performance and space efficiency. Compressed data may be bigger than the original data for small data. If compression is meaningless, CPU power for compression is also meaningless.

Conclusions
