Mathias: That is excellent advise. Still learning feature by feature.

But if you KNOW that M's seq N has already made its way via I to the Rs, you can use that seq N as a start seq parameter for a new replication between M and the Rs. e.g. curl -sg -X POST 'http://sourceHost:5984/_replicate' -H 'Content-Type:application/json' -d '{ "source":"sourceDB", "target":"http://targetHost:5984/targetDB";, "filter":"filters_erl/no_design", "continuous":true, "since_seq":59210797 }' - mathias On Jul 12, 2012, at 1:43 , Andreas Kemkes wrote: > To speed up the process of breaking up one monolithic database into > multiples, I used an intermediate database to get to the end result: > > > > M -- pre-filtered replication --> I -- 1..n filtered replications --> > R1..n > > > Afterwards I tried to set up continuous filtered replications directly > between M and R1..n.
