Subject [jira] [Updated] (SOLR-6460) Keep transaction logs around longer
Date Tue, 30 Sep 2014 17:25:34 GMT

     [ https://issues.apache.org/jira/browse/SOLR-6460?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Renaud Delbru updated SOLR-6460:
--------------------------------
    Attachment: SOLR-6460.patch

A new patch that introduces efficient seeking over a list of transaction log files. Efficient
seeking is achieved by adding metadata (version number) to tlog filename and by leveraging
the filesystem's index. The tlog filename has now the following syntax: "tlog.${logId}.${startVersion}".

> Transaction logs are currently deleted relatively quickly... but we need to keep them
around much longer to be used as a source for cross-datacenter recovery.  This will also be
useful in the future for enabling peer-sync to use more historical updates before falling
back to replication.
