Piotr Nowojski commented on FLINK-14884:
----------------------------------------
Have you looked at
{{org.apache.flink.streaming.api.checkpoint.ExternallyInducedSource}}? It
allows sources to trigger checkpoints manually.
Keep in mind that this {{@PublicEvolving}} API, that is also currently being
slightly modified. In Flink 1.10 {{MasterTriggerRestoreHook#triggerCheckpoint}}
is required to be non blocking - you can take a look at FLINK-14344 (especially
release notes).

> Hi,
> I wish to have control on checkpoint trigger time and interval time behavior
