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
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
