Hi Alex

First of all, RocksDB is not created by Flink checkpoint mechanism. RocksDB would be launched once you have configured and use keyed state no mater whether you have ever enabled checkpoint.

If you want to check configuration and data in RocksDB, please login the task manager node. The RocksDB folder lies in Flink temporary dir [1] which looks like flink-io-xxxx and the configuration is located in the file named as 'LOG' with RocksDB directory.

If you have specified the LOCAL_DIRECTORIES[1] , then the LOG will go into the LOCAL_DIRECTORIES.
