Subject [jira] [Created] (COUCHDB-1874) Continuous replication slows down over time
Date Tue, 20 Aug 2013 17:02:51 GMT
Joan Touzet created COUCHDB-1874:

             Summary: Continuous replication slows down over time
                 Key: COUCHDB-1874
             Project: CouchDB
          Issue Type: Bug
          Components: Replication
            Reporter: Joan Touzet

As reported on the mailing list:

bq. > Did you specify "continuous": true in the replication spec?  If you did, do you see
the same slowdown if you omit that flag?

bq. > This sounds rather similar to a bug we encountered in early builds of BigCouch, but
I don't remember the history of the codebase well enough to say whether the bug might be latent
in Apache CouchDB.

bq. Yes, I was using "continuous": true.

bq. You're right: When disabling "continuous", replication seems more stable and efficient
(1200 doc/sec). Thank you !

And, from IRC:

bq. 12:54 <+rnewson> iirc the cause we found was an unconsumed event message that gradually
fills the mailbox, which sounds like it ought to affect couchdb.
