Subject [jira] [Commented] (SOLR-1426) Allow delta-import to run continously until aborted
Date Fri, 31 Aug 2012 21:37:08 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13446398#comment-13446398
] 

Abdul Chaudhry commented on SOLR-1426:
--------------------------------------

I would avoid using the DIH for incremental updates. You need to be careful synchronizing
with an eventually consistent database. I would go to the 'source' that manages the updates/inserts
before they even get to the database and push to SOLR from the source.

> Modify the delta-import so that it takes a perpetual flag that makes it run continuously
until its aborted.
> http://localhost:8985/solr/select/?command=delta-import&clean=false&qt=/dataimport&commit=true&perpetual=true
> perpetual means the delta import will keep running and pause for a few seconds when running
queries.
> The only way to stop delta import will be to explicitly issue an abort like so:-
> http://localhost:8985/solr/tickets/select/?command=abort
