Ryan McKinley commented on SOLR-906:
------------------------------------

I suppose...  though I don't see it as a strict requirement -- if you need full 
error handling, use a different SolrServer implementation.

I think a more reasonable error API would be a callback function rather then 
polling -- the error could occur outside you loop (assuming you break at some 
point).  That callback could easily be converted to a polling api if desired.

The big thing to note with this API is that calling:
 solr.add( doc )
just adds it to the queue processes it in the background.  It is a 
BlockingQueue, so after it hits the max size the client will block before it 
can add -- but that should be transparent to the client.

the error caused by adding that doc may happen much later in time.

I'll go ahead and add that callback...

> While indexing lots of documents, the CommonsHttpSolrServer add( 
> SolrInputDocument ) is less then optimal.  This makes a new request for each 
> document.
> With a "StreamingHttpSolrServer", documents are buffered and then written to 
> a single open Http connection.
