Re: How do I initialize the window state on first run?

Hi, vivo,

    My Flink program is to aggregate the data of a whole day, assume we start this program on 6:00 am, the default state in the window should be the aggregated result of 0:00 am to 6:00 am.

Hi Jiayi,

If you don't mind, I would like to ask you what kind of situation do you have in this situation?

Thanks, vino.

   I’m going to run a new Flink program with some initialized window states. 

   I can’t see there is an official way to do this, right? I’ve tried the bravo project, but it doesn’t support FsStateBackend and it costs too much work if we add a new StateBackend in it. 

   Any good ideas about this?
