[jira] [Commented] (CASSANDRA-7772) Windows - fsync-analog, flush data to disk

    [ https://issues.apache.org/jira/browse/CASSANDRA-7772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14118753#comment-14118753 ] 

Jonathan Ellis commented on CASSANDRA-7772:
-------------------------------------------

> We currently use CLibrary fsync linux-native calls to flush to disk.  Given the role this plays in our SequentialWriter and data integrity in general we need some analog to this function on Windows.
