> Hi,
> I wish to have control on checkpoint trigger time and interval time behavior by user defined function.
> For some cases I would like to skip checkpoint during a certain hour or certain minutes or vice versa.
> And some cases during several hours I would like to increase checkpoint interval.
> And some case A crontab style could be used simply.
