> Savepoint can take much longer time to perform than checkpoint, especially with incremental checkpoint enabled. This leads to a couple of troubles:
> * For our job, we currently have to set the checkpoint timeout much large than necessary, otherwise we would be unable to perform savepoint.
> * During rush hour, our cluster would encounter high rate of checkpoint timeout due to backpressure, however we're unable to migrate to a larger configuration, because savepoint also timeout.
> In my opinion, the timeout for savepoint should be configurable separately, both in the config file and as parameter to the savepoint command.
