> 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?
