Subject [jira] [Commented] (SOLR-1726) Deep Paging and Large Results Improvements
Date Thu, 13 Oct 2011 17:43:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13126749#comment-13126749
] 

Ryan McKinley commented on SOLR-1726:
-------------------------------------

bq Ideally Solr would allow SolrJ to stream the results. 

Check:
[SolrServer.html#queryAndStreamResponse|https://builds.apache.org/view/G-L/view/Lucene/job/Solr-trunk/javadoc/org/apache/solr/client/solrj/SolrServer.html#queryAndStreamResponse(org.apache.solr.common.params.SolrParams,
org.apache.solr.client.solrj.StreamingResponseCallback)]

I have used it with up to 1M docs without much issue...

> There are possibly ways to improve collections of "deep paging" by passing Solr/Lucene
more information about the last page of results seen, thereby saving priority queue operations.
  See LUCENE-2215.
> There may also be better options for retrieving large numbers of rows at a time that
are worth exploring.  LUCENE-2127.
