> Enable limiting RocksDB memory consumption by default. This means to change the default value of {{state.backend.rocksdb.memory.managed}} to {{true}}. This will change Flink's default behaviour for many users but I believe the benefits of a much more predictable memory behaviour of Flink will outweigh the downside of having fewer memory available.
