Subject [jira] [Commented] (CASSANDRA-3668) Performance of sstableloader is affected in 1.0.x
Date Thu, 14 Jun 2012 16:03:43 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13295130#comment-13295130

Sylvain Lebresne commented on CASSANDRA-3668:
---------------------------------------------

I believe this is a parallel improvement to CASSANDRA-4297 so it's not made irrelevant by
it per-se (I'm talking of Yuki's patch, not of the ticket title).

> One of my colleague had reported the bug regarding the degraded performance of the sstable
generator and sstable loader.
> ISSUE :- https://issues.apache.org/jira/browse/CASSANDRA-3589 
> As stated in above issue generator performance is rectified but performance of the sstableloader
is still an issue.
> 3589 is marked as duplicate of 3618.Both issues shows resolved status.But the problem
with sstableloader still exists.
> So opening other issue so that sstbleloader problem should not go unnoticed.
> FYI : We have tested the generator part with the patch given in 3589.Its Working fine.
> Please let us know if you guys require further inputs from our side.
