Yes…that’s an option, but it’ll be very complicated because of our storage and business. Now I’m trying to write an handler like the “KvStateHandler” so that I can access(read/write) the state from my client.

IIUC, we can't initialize state at first run, maybe you could store the aggregated data in another place other than use flink's state, then use flink to aggregate the data realtime. bupt_ljy bupt_...@163.com 于2018年10月12日周五 下午3:33写道： 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. bupt_ljy bupt_...@163.com 于2018年10月12日周五 下午1:59写道： Hi, 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?
