[jira] [Updated] (SOLR-11483) Keep more transaction log files when
maxNumLogsToKeep is specified
[ https://issues.apache.org/jira/browse/SOLR-11483?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Cassandra Targett updated SOLR-11483:
-------------------------------------
Component/s: SolrCloud
> Keep more transaction log files when maxNumLogsToKeep is specified
> ------------------------------------------------------------------
>
> Key: SOLR-11483
> URL: https://issues.apache.org/jira/browse/SOLR-11483
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Reporter: Varun Thacker
> Priority: Major
>
> We allow users to control the number of transaction log files the system should keep ( maxNumLogsToKeep ) and the number of records to keep ( numRecordsToKeep )
> However just by setting numRecordsToKeep we are not guaranteed that the system will actually keep that many records.
> This comment explains why - https://issues.apache.org/jira/browse/SOLR-6359?focusedCommentId=15214361&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15214361
> A tradeoff would be if a user explicitly specifies numRecordsToKeep and doesn't specify maxNumLogsToKeep then we should use a higher default for maxNumLogsToKeep ( say 1000 instead of 10 today )
> Off course better documentation will help so if others think this is a bad idea then we can close this out and just make sure it's documented and if users know about one parameter they will know about the other parameter as well
