jackylau created FLINK-14159: -------------------------------- Summary: flink rocksdb StreamCompressionDecorator not right Key: FLINK-14159 URL: https://issues.apache.org/jira/browse/FLINK-14159 Project: Flink Issue Type: Bug Components: Runtime / State Backends Affects Versions: 1.9.0 Reporter: jackylau Fix For: 1.10.0
I think the current flink rocksdb StreamCompressionDecorator is not right 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? -- This message was sent by Atlassian Jira (v8.3.4#803005)
