Subject [jira] Updated: (DERBY-3562) Number of log files (and log dir size) on the slave increases continuously
Date Wed, 26 Mar 2008 07:53:25 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3562?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jørgen Løland updated DERBY-3562:
---------------------------------

    Attachment: derby-3562-1a.stat
                derby-3562-1a.diff

Patch 1a deletes unnecessary, old log files on the slave when a checkpoint is encountered
in the log received from the master. All tests (except those failing tinderbox) passed, including
the replication test suite.

Requesting review.

> I did a simple test inserting tuples in a table during replication:
> The attached file 'master_slave-db_size-6.jpg' shows that 
> the size of the log directory (and number of files in the log directory)
> increases continuously during replication, while on master the size 
> (and number of files) never exceeds ~12Mb (12 files?) in this scenario.
> The seg0 directory on the slave stays at the same size as the master 
> seg0 directory.
