[jira] [Commented] (RATIS-617) StateMachine#takeSnapshot should pass the log index at which the snapshot should be taken

    [ https://issues.apache.org/jira/browse/RATIS-617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16881449#comment-16881449 ] 

Tsz Wo Nicholas Sze commented on RATIS-617:
-------------------------------------------

If StateMachine#takeSnapshot passes the log index, it seems that the state machine needs to maintain all the indices in order to take the snapshot.  I am not sure how to make it works.  :)
