Des Lownds updated LUCENE-3953:
-------------------------------
Attachment: FieldCacheLimitPatch.patch
imports fixed. Patch applies to lucene-solr 4.0 checked out from
http://svn.apache.org/repos/asf/lucene/dev/trunk
> Using many dynamic fields in filters, sorts causes OOM
> ------------------------------------------------------
>
> Key: LUCENE-3953
> URL: https://issues.apache.org/jira/browse/LUCENE-3953
> Project: Lucene - Java
> Issue Type: Bug
> Components: core/search
> Affects Versions: 4.0
> Reporter: Des Lownds
> Attachments: FieldCacheLimitPatch.patch
>
>
> I have an index with ~1M documents, and many uniquely named fields. Each
> document only has a few fields populated, but there is a large set of dynamic
> fields across all docs. In other words, theres many sparse fields.
> Eventually the jvm will fall over due to OOM errors, because lucene's
> fieldCache grows without bounds. Adding more heap does not help.
