It's possible that Peter's comment on autocommit for the initial
update-discovery-index still needs to be changed.
> Ability to perform maintenance on SOLR with solr.optimize
> ---------------------------------------------------------
>
> Key: DS-615
> URL: https://jira.duraspace.org/browse/DS-615
> Project: DSpace
> Issue Type: Improvement
> Components: Solr
> Environment: solr
> Reporter: Peter Dietz
> Assignee: Ben Bosman
> Fix For: 1.8.0
>
> Attachments: search-solr-optimize-quick-and-dirty.patch,
> SolrOptimizeAndAutoCommit.patch, solr-optimize.patch
>
>
> By adding all historical log data to a SOLR index, as well as the constant
> addition of new records, it might be good for the efficient performance of a
> SOLR index to periodically run solr.optimize.
> Therefore I've created a patch which allows you to run solr.optimize on your
> solr instance from the command line. This could allow you to add a cron task
> that runs this periodic maintenance. It also spits out the amount of time
> taken to run the optimize task.
> Once you patch your instance. You can execute this with
> /dspace/bin/dspace stats-util --optimize
> or
> /dspace/bin/dspace stats-util -o
> Output looks like:
> SOLR Optimize -- Process Started:1277486321673
> SOLR Optimize -- Process Finished:1277486321738
> SOLR Optimize -- Total time taken:65 (ms).
> It would be useful to profile the amount of time taken for solr operations
> add/update/query before running this optimize task, and then afterwards.
