Subject [jira] [Updated] (SOLR-2701) Expose IndexWriter.commit(Map<String,String> commitUserData) to solr
Date Thu, 29 Nov 2012 03:18:58 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2701?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Greg Bowyer updated SOLR-2701:
------------------------------

    Attachment: SOLR-2701-Expose-userCommitData-throughout-solr.patch

I gave this another attempt today, and went full bore on trying to find all the locations
of where userCommitData would need to be exposed to clients of the SOLR API.

There are a few questions in my mind about this:

* The backwards compat for javabin is not obvious, do we want to change up the version on
javabin

* What should be the exacting behavior around soft and autocommits

* Should previous index commits carry forward in solr for ease of use ?

> At the moment, there is no feature that enables associating user information to the commit
point.

> Lucene supports this possibility and it should be exposed to solr as well, probably via
beforeCommit Listener (analogous to prepareCommit in Lucene).
> Most likely home for this Map to live is UpdateHandler.
> Example use case would be an atomic tracking of sequence numbers or timestamps for incremental
updates.
