Subject [jira] [Commented] (CASSANDRA-10015) Create tool to debug why expired sstables are not getting dropped
Date Mon, 10 Aug 2015 08:49:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14679812#comment-14679812
] 

Marcus Eriksson commented on CASSANDRA-10015:
---------------------------------------------

bq. Do we need a Windows script and why do we have some sstable* scripts in bin and some in
tools/bin?
I will add one in 2.1 as that is where we started supporting Windows
bq. In the documentation at the top of SSTableExpiredBlocker I would reference the ticket
number and perhaps explicitly spell out how an sstable can block expired sstables, rather
than just limiting it to "cover anything in other sstables". Something like what's mentioned
in this ticket description would maybe be a little clearer.
done
bq. I would replace columnfamily with table, at least in the usage and error messages.
fixed, will rename variables in 3.0+

> Sometimes fully expired sstables are not getting dropped, and it is a real pain to manually
find out why.
> A tool that outputs which sstable blocks (by having older data than the newest tombstone
in an expired sstable) expired ones would save a lot of time.
