Subject [jira] [Commented] (CONNECTORS-1497) Re-index seeded modified documents when the re-crawl interval is infinity and connector model is MODEL_ADD_CHANGE
Date Tue, 27 Feb 2018 08:29:00 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16378229#comment-16378229
] 

Karl Wright commented on CONNECTORS-1497:
-----------------------------------------

Thinking further: continuous crawling was designed originally for web crawling.  We really
do not want to override the document schedule on document rediscovery in that case; the current
behavior is correct.  It's only for MODEL_ADD_CHANGE_DELETE where we want to do that, and
people don't use that with continuous crawling today.

Ok -- so I think if the connector model is ADD_CHANGE_DELETE, a proper implementation should
do several things:
(1) Force the recrawl interval to infinity, and/or disable its display in the UI, for all
continuous jobs based on MODEL_ADD_CHANGE_DELETE connectors.
(2) Change the behavior of seeding and document discovery through ISeedingActivity and IProcessActivity
to clear the document schedule ONLY when the underlying connector model is MODEL_ADD_CHANGE_DELETE
or MODEL_CHAINED_ADD_CHANGE_DELETE.

I'd be happy with a suite of changes of that kind.

> Trying to avoid a full scan of all documents for a better efficiency with a large number
of documents. I tried so many different setting for the Jobs but I couldn't accomplish that.
Especially when the repository connector model is MODEL_ADD_CHANGE I was expecting the modified
documents seeded should be re-indexed immediately similar to the new seeds but I found out
it uses the re-crawl time as the scheduled time and it waits for the full scan to get re-indexed.
I avoided full scan by setting the re-crawl interval to infinity but still, my modified documents
seeds were not getting indexed. After digging into the code for quite good time. I did some
modification to the JobManager and it worked for me. I would like to share the change with
you for review so I opened this ticket.
