Simon Rosenthal commented on SOLR-2664: --------------------------------------- In working on extending the functionality to SolrJ/CSV/JSON, I've seen some shortcomings and ambiguities in the initial API I was working on. here's a clearer approach: The anticipated use case would be to disable autocommits temporarily during update processing from a content stream (or from a server.add() in solrJ). So for /update handlers where a content stream is specified, append the parameter &deferAutoCommit=true to the URL. Autocommits will be disabled while the content stream is processed, and automatically re-enabled at the end of processing (regardless of success or failure). This will also be a recognized attribute in an <add> element for solr XML processing. Additionally, no content stream is specified, one can specify the single operations /update?disableAutoCommit=true and subsequently /update/enableAutoCommit=true, in the same way as you can specify commit as the only parameter. However you're on your own if you do the one without the other.... SolrJ will have new server#disableAutoCommit and server#enableAutocommit methods, and also add(doc, boolean deferAutoCommit). > Disable/enable autocommit on the fly > ------------------------------------ > > Key: SOLR-2664 > URL: https://issues.apache.org/jira/browse/SOLR-2664 > Project: Solr > Issue Type: New Feature > Components: update > Affects Versions: 4.0 > Reporter: Simon Rosenthal > Priority: Minor > Fix For: 4.0 > > Attachments: SOLR-2664.patch > > > There are occasions when although autocommit is configured, it would be > desirable to disable it temporarily - for instance when batch adding/updating > a set of documents which should be committed atomically (e.g. a set of price > changes). > The patch adds <disableAutoCommit/> and </enableAutoCommit> commands to > XMLUpdateHandler, and also adds a disableAutoCommit=true|false attribute to > the <add> element - this will disable autocommit until the terminating </add> > at the end of the XML document is reached. > At present, the autocommit state will not survive a core reload. > It should be possible to extend this functionality to SolrJ, CSVUpdatehandler > ( and JSONUpdateHandler ?) -- This message is automatically generated by JIRA.
