Subject [jira] [Commented] (CASSANDRA-7772) Windows - fsync-analog, flush data to disk
Date Thu, 14 Aug 2014 21:20:19 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14097679#comment-14097679
] 

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

We use CLibrary.trySync not because it performs better than FileDescriptor.sync, but because
FD.sync doesn't sync the parent directory. (CASSANDRA-3250)

> 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.
