Noble Paul updated SOLR-486:
----------------------------

    Attachment: SOLR-486.patch

No changes . Just synchronizing with other code changes.

This is a  very useful option for users who wish to implement a binary format 
to improve the performance. (I plan to contribute one as soon as this is 
committed)

Currently the java clients go though the xml response format which can eat up 
some time in unmarshalling . It can be quite significant if the document size 
is large (take the case of facet requests)

I have an xml reponse which took around 30ms for unmarshalling . Binary format 
would have taken less than 5 ms.

> QueryResponse writer only allows text data to be written.
> So it is not possible to implement a binary protocol . Create another 
> interface which has a method 
> write(OutputStream os, SolrQueryRequest request, SolrQueryResponse response)
