Subject [jira] Commented: (SOLR-906) Buffered / Streaming SolrServer implementaion
Date Tue, 16 Dec 2008 19:02:44 GMT

    [ https://issues.apache.org/jira/browse/SOLR-906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12657115#action_12657115

Shalin Shekhar Mangar commented on SOLR-906:
--------------------------------------------

bq. why not? All the tests pass for me... 
There are multiple places where SolrExampleTest calls commit without waitSearcher=true and
proceeds to query and assert on results. The failure happens intermittently. Try varying the
number of threads and you may be able to reproduce the failure.

bq. The add calls do not come to the process method.
I meant the request method. Sorry about that. The SolrServer.add() calls the request method
but this implementation does not. If there are multiple threads using this class, new documents
may get added to the queue before we acquire the lock inside blockUntilFinished due to the
call to commit.

> 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.
