Real time streaming spark apps especially stateful streaming cloud apps can take up significant times with state checkpointing to S3.Here at IMG Arena, we used EFS backed PVC(ReadWriteMany) mounted on to driver and executors as checkpoint storage which improved our latencies up to 2 seconds.We use RocksDBStateStoreProvider and gained a significant improvement in rocksdbCommitFileSyncLatencyMs metric from 2.9sec to 0.76 sec gaining around ~2 sec. The EFS state store seamlessly works during auto scaling , spot executor termination ,state load up time on new/different executors .The EFS backed PVC also speeds up meta data checkpointing for commits and offsets tracking.
