Subject [jira] [Commented] (SOLR-1426) Allow delta-import to run continously until aborted
Date Fri, 31 Aug 2012 14:45:08 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13446007#comment-13446007
] 

James Dyer commented on SOLR-1426:
----------------------------------

This sort of thing is needed for sure, especially now that we have such good NRT support in
4.0.  But the patch here is shortsighted as it works only with the delta import command (you
can do incremental updates with "full-import" ; often its the better choice).  I'm also not
sure I like the approach of putting the DIH handler thread in a perpetual loop and having
it sleep a few seconds in between each iteration.  

Unless someone objects, I want to mark this as "won't fix/duplicate" and I think we need to
work on SOLR-2305 or something like it instead.

> 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:-
