I'm trying to decide whether to set-up RocksDB now or later. The state for my Flink jobs right now will be able to fit into memory, so I can use the filesystem state backend. In a few months time it is likely the state will no longer fit into memory, so I will want to use the RocksDB backend.
I was just wondering if it's possible/easy to use savepoints to migrate existing state from the filesystem backend to the RocksDB backend? As I would not want to lose any job state when switching to RocksDB. If there's a way to do it then I can worry about RocksDB later. Thanks! Josh
