> I think the current flink rocksdb StreamCompressionDecorator is not right
> when calling method
> getCompressionDecorator(executionConfig) ,which defalut value is false.That
> is to say, current compression is none.But I find rocksdb using
> {{options.compression}} to specify the compression to use. By default it is
> Snappy, which you can see here
> [https://github.com/facebook/rocksdb/wiki/RocksDB-Tuning-Guide]. And I use
> rocksdb tool sstdump to find it is indeed snappy compression.
> So I think it should be return SnappyStreamCompressionDecorator.INSTANCE
> rather than getCompressionDecorator( executionConfig)
> Coud i commit a PR?
