[jira] [Commented] (IOTDB-2084) Change last flush time granularity from device to timeseries

    [ https://issues.apache.org/jira/browse/IOTDB-2084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17465514#comment-17465514 ] 

Kaifeng Xue commented on IOTDB-2084:
------------------------------------

For performance reason (doc is here: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=199529203). We will not change granularity but manage flush time by id table.
