Subject [jira] [Updated] (SOLR-2700) transaction logging
Date Thu, 25 Aug 2011 14:47:29 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2700?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yonik Seeley updated SOLR-2700:
-------------------------------

    Attachment: SOLR-2700.patch

Here's an update that uses a fixed set of external strings in the javabin codec to ret and
avoid repeating all of the field names in the logs.  This drops the indexing penalty to 28%
slower in this specific test, and decreases the transaction log size to 974M.

> A transaction log is needed for durability of updates, for a more performant realtime-get,
and for replaying updates to recovering peers.
