our application is stateful. processing live events depends on the
state. but for kinds of reason, we need rebuild the state. it will be very
costly to replay all data.
our historical events data are stored in s3. so we want to create
states/savepoints periodically so that we can rebuild the state from a point.
we call this as a bootstrap process.
any ideas?
Thanks.

Subject:Re: create savepoint on bounded source in streaming mode
Hi, Shawn
I think Flink does not support this mechanism yet.
Would you like to share the scenario in which you need this savepoint at the
end of the bounded input?
Best,

Hi experts,
assume I have several files and I want replay these files in order in streaming
mode and create a savepoint when files play at the end. it is possible?
I wrote a simple test app, and job are finished when source is at the end. I
have no chance to creat a savepoint. please help.
Thanks
