Howto delay view requests until indexes are rebuilt

[Alex Schenkman <al...@schenkman.info>]

Hi list,

According to what I see in the logs and the results I get, the following
might be happening. Given that:

1) I update a document (using an update handler)
2) Couch starts an index update
3) I request a view
4) I get the "old" view results
5) Couch finnish its re-indexing
6) I request the same view again
7) I get the new view results

I understand why this is happening, but in my use case, I woud prefer couch
delaying the answer to the view request, until the index is rebuilt.
Is it possible to tell couch to behave this way?
I could not find any setting for this in the config file.

Thanks in advance!

Hi Alex,

CouchDB does not update indexes until you query the view. The behaviour you are asking for is the default behaviour (that the view reflects the current state of the database). stale=ok is "don’t update the view" and stale=update_after is "update the view after *this* query".

As Stanley notes, you must be supply stale=ok or stale=update_after in order to reach your step 4.

So the default behavior us to wait until it's finished for that sequence
particular request. Can you send the exact query you're making... Are you
passing stale=OK?
