[jira] [Updated] (SOLR-3142) remove O(n^2) slow slow indexing defaults in DataImportHandler

["Robert Muir (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-3142?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Muir updated SOLR-3142:
------------------------------

    Attachment: SOLR-3142.patch

patch for the optimize.

I agree about the soft commit, if not even the default it should at least be allowable/configurable... but I just didn't implement this in the patch.

In general whatever options are available for commit should be consistent with what DIH allows, maybe we should open a separate issue to ensure this is the case.

> By default, dataimporthandler optimizes the entire index when it commits.
> This is bad for performance, because it means by default its doing a very
> heavy index-wide operation even for an incremental update... essentially 
> O(n^2) indexing.
> All that is needed is to set optimize=false by default. If someone wants
> to optimize, they can either set optimize=true or explicitly optimize themselves.
