Wind updated BAHIR-146:
-----------------------
Description:
It seems that the redis sink is not very suitable for some specific
circumstances.
For example, I want to do a word count and I enable the checkpoint machenism,
it seems to be wrong if I start my program from checkpoint when my program
fails, because some data that already sent will be sent to redis sink again.
