David Smiley commented on SOLR-5154:
------------------------------------
Is the description not clear? I've got client code that takes a SolrServer
that might either be EmbeddedSolrServer or some other variant. I'd like to
stream the docs if possible, so I use the StreamingResponseCallback feature.
Yet apparently that only works with EmbeddedSolrServer, which I think was a
major oversight in the API.
My work around now is:
{code:java}
QueryRequest queryRequest = ...
queryRequest.setStreamingResponseCallback( ... );
QueryResponse response = queryRequest.process(solrServer);
SolrDocumentList docList = response.getResults();
if (docList != null) {
log.debug("Not streaming docs from Solr (not supported)");
StreamingResponseCallback callback = tagRequest
.getStreamingResponseCallback();
callback.streamDocListInfo(docList.getNumFound(),
docList.getStart(), docList.getMaxScore());
for (SolrDocument solrDoc : docList) {
callback.streamSolrDocument(solrDoc);
}
}
{code}
> StreamingResponseCallback should be used by non-Embedded solr servers too
