[jira] [Commented] (BEAM-2393) BoundedSource is not fault-tolerant in FlinkRunner Streaming mode

    [ https://issues.apache.org/jira/browse/BEAM-2393?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16031150#comment-16031150 ]

----------------------------------------

Ha! This is true. I'm wondering what we could do, since the {{BoundedSource}} interface doesn't have a "snapshot" method or something else to that effect.

> {{BoundedSourceWrapper}} does not implement snapshot() and restore(), when the failure to restart, it will send duplicate data.
