Hi, I'm running Flink job in distributed mode deployed in Yarn; I've enabled externalized checkpoint to save in Hdfs, but I don't have access to read checkpoints folder. To restart Flink job from the last saved checkpoint is it possible to do without passing "-s :checkpointPath". If this is not po

Externally load data into RocksDB backend

Hi, Is it possible to load data to RocksDB backend externally(outside Flink ) using common dbPath, so that it will be available to MapState inside ProcessFunction. I've external data available in JSON format which I want to load to RocksDb. One option is to make Stream from the JSON path and proc
