[jira] [Commented] (IOTDB-3427) Make snapshot thread-safely

    [ https://issues.apache.org/jira/browse/IOTDB-3427?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17553358#comment-17553358 ] 

Song Ziyang commented on IOTDB-3427:
------------------------------------

Currently, Ratis called SM's write & takeSnapshot in following code:

Thus, takeSnaphot() and write() operation is strictly serial and don't have concurrency issues.
