[jira] [Updated] (BAHIR-146) repeated data sink to redis

     [ https://issues.apache.org/jira/browse/BAHIR-146?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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 will be sent to redis sink.
