Hi Stephan, I am observing similar issue with Flink 1.2.1
The memory is continuously increasing and data is not getting flushed to disk. I have attached the snapshot for reference. Also the data processed till now is only 17GB and above 120GB memory is getting used. Is there any change wrt RocksDB configurations <http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/file/n14013/TM_Memory_Usage.png> Regards, Vinay Patil -- View this message in context: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Re-Checkpointing-with-RocksDB-as-statebackend-tp11752p14013.html Sent from the Apache Flink User Mailing List archive. mailing list archive at Nabble.com.
