Subject [jira] [Commented] (CASSANDRA-5444) TTL does not compact rows
Date Tue, 09 Apr 2013 08:22:15 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5444?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13626381#comment-13626381
] 

Jeremy Hanna commented on CASSANDRA-5444:
-----------------------------------------

Brandon: to be clear, they saw that when they did the alter table command, it would continue
to have the range ghost after the ttl + gc_grace + flush + compact.  However if they create
a new column family with that gc_grace and do the same process, the range ghost is no longer
there.

> I find that the rows are not compacted when gc_grace_seconds is set through alter table
command. Following were the steps performed:
> 1. Created the following table:
> CREATE COLUMNFAMILY MirrorSmokeTest (
>     id uuid PRIMARY KEY,
>     test_message varchar
> );
> 2. Ran an alter command:
> alter table MirrorSmokeTest WITH gc_grace_seconds = 60;
> 3. Insert a row into the above table:
> insert into MirrorSmokeTest (id, test_message) Values ('4a7fad82-8298-4d91-85de-8255b7c7e4f5',
'2') USING ttl 60;
> 4. Waited for 60 seconds and ran a query that results in the following output:
>  select * from MirrorSmokeTest;
>  id
> --------------------------------------
>  4a7fad82-8298-4d91-85de-8255b7c7e4f5
> 5. Ran a flush and compact and reran the query that results in the following:
>  select * from MirrorSmokeTest;
>  id
> --------------------------------------
>  4a7fad82-8298-4d91-85de-8255b7c7e4f5
