[jira] Commented: (SOLR-906) Buffered / Streaming SolrServer implementaion

["Ryan McKinley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12655298#action_12655298 ] 

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

One basic problem with calling add( SolrInputDocument) with the CommonsHttpSolrServer is that it logs a request for each document.  This can be a substantial impact.  For example while indexing 40K docs on my machine, it takes ~3 1/2 mins.  If I turn logging off the time drops to ! 2 1/2 mins.  With the streaming approach, the time drops to 20sec!   Some of that is obviously because it limits the logging:
{code}
INFO: {add=[id1,id2,id3,id4, ...(38293 more)]} 0 20714
{code}

> 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.
