-----------------------------------------
Resolution: Won't Fix
> Clear root Entity cache when entity is processed
> ------------------------------------------------
>
> Key: SOLR-2313
> URL: https://issues.apache.org/jira/browse/SOLR-2313
> Project: Solr
> Issue Type: Improvement
> Components: contrib - DataImportHandler
> Affects Versions: 1.4.1
> Environment: Linux, JDBC, Postgres 8.4.6
> Reporter: Shane
> Assignee: Alexandre Rafalovitch
> Priority: Major
>
> The current process clears the entity caches once all root entity elements
> have been imported. When a config file has dozens of root entities, the
> result is one "idle in transaction" process for each entity processed,
> effectively eating up the databases available connections. The simple
> solution would be to clear a root entity's cache once that entity has been
> processed.
> The following is a diff that I used in my instance to clear the cache when
> the entity completed:

> +++ DocBuilder.java.new 2011-01-12 10:05:31.000000000 -0700

> writer.log(SolrWriter.END_ENTITY, null, null);
> }
> entityProcessor.destroy();
> + if(entity.isDocRoot) {
> + entity.clearCache();
> + }
> }
> }
