Hi [~godfrey] Is it possible to provide your sample code that could reproduce
this? I think that could be helpful.

> I used RocksDBStateBackend to checkpoint for my job, and it always failed for
> timeout. But when I closed CEP, only keeped the source operator, which was
> working fine. And FsStateBackend was also finished checkpoint quickly without
> timeout.
