I think that could be helpful. > Flink CEP with Checkpointing alway failed > ----------------------------------------- > > Key: FLINK-9175 > URL: https://issues.apache.org/jira/browse/FLINK-9175 > Project: Flink > Issue Type: Improvement > Components: State Backends, Checkpointing > Affects Versions: 1.4.1 > Environment: * Checkpoint Interval: 1min > * Checkpoint Timeout: 2min > * Checkpoint Pause: 5s > * Checkpoint Concurrent: 1 > * Checkpoint Mode: EXACTLY_ONCE > * AllowedLateness: 100s > * CEP within time: 30s > * Kafka QPS:10,000 > * Source Parallelism: 16 > > Reporter: godfrey johnson > Priority: Major > Attachments: checkpoint failed.png, dataStream.png > > > I used RocksDBStateBackend to checkpoint for my job, and it always failed for > timeout.
