Hi,
We configure rocksdb as statebackend and checkpoint dir persists to hdfs. When the job is run, rocksdb automatically mount to tmpfs /tmp, which consume memory. RocksDBStateBackend rocksdb = new RocksDBStateBackend(new FsStateBackend(hdfs://), true); env.setStateBackend(rocksdb); Questions, 1. What happen if large state is larger than the tmpfs memory size? Will flink do something? 2. Is it possible to configure rocksdb dir via flink? Thank you. Regards, Yow
