Sean Timm commented on SOLR-457:
--------------------------------
Currently with Solrj, if you want to take advantage of the connection pooling,
I think you need to create a single instance of CommonsHttpSolrServer in your
application (and if you aren't, you are better off using
SimpleHttpConnectionManager). So, it seems to make sense to make it easier to
use in this fashion. This could be made more general purpose though if process
just took a single request and returned a single response and you called it
once for each server. This would abstract out the threading and connection
pooling while not constraining the class to something designed primarily for
SOLR-303.
A couple of other comments:
The threads should probably be pooled rather than creating and destroying on
each request. While creating and destroying threads has gotten faster, pooling
is usually beneficial.
Unless I'm mistaken, it appears that your connectionManager is different from
the _connectionManager in CommonsHttpSolrServer, so the methods that you didn't
override will not work correctly, e.g., setConnectionTimeout().
Neither the CommonsHttpSolrServer currently in Solrj nor this patch appear to
allow setting of the read timeout: setSoTimeout(int timeout) or the connection
manager timeout: setConnectionManagerTimeout(long timeout). Other HttpClient
options such as disabling Nagle's algorithm are probably not as important.
This should probably be opened as a separate JIRA issue.
