> LogSearch: Need to decrease mergeFactor to enable purge of documents more
> often
> -------------------------------------------------------------------------------

> Key: AMBARI-16110

> Project: Ambari
> Issue Type: Bug
> Reporter: Don Bosco Durai
>
> LogSearch deletes logs older than 7 days (by default). The indexed documents
> doesn't get purged until the segments are merged. Currently the mergeFactor
> is 25, which is pretty large. If documents are not purged, then the indexes
> occupy disk and memory.
> It is better to make the mergeFactor value to be 5 and let Solr purge deleted
> documents more regularly.
> The following 2 files needs to be updated:
> ambari-server/src/main/resources/common-services/LOGSEARCH/0.5.0/properties/audit_logs-solrconfig.xml.j2
> ambari-server/src/main/resources/common-services/LOGSEARCH/0.5.0/properties/service_logs-solrconfig.xml.j2
