Description

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.
