Hi guys,
I'm on CouchDB 0.9.1 and here is what I am trying to do:
- node A, database A (docs have a node flag)
- node B, database B (docs have a node flag)
- node C, database C
I need db A to replicate to db C and db B to replicate to C.
However I want C to only replicate documents flagged for each node.
The problem with using validation for replication is that it simply
doesn't
work. The view validation requires that you throw an exception if the
document isn't valid, when you replicate 40,000 documents, couch just
crashes on you. Worse, if you replicate two document and one fails
the
validation, none get replicated.
0.10 seems to have a filtering system, but it seems to be working
exactly
like validation.
This is quite a big problem for the project I'm working on, can
anyone
suggest a better way to deal with this issue?
The _changes filter is the correct way to do this.
I'm not sure of the exact status of the implementation in 0.10. My
guess is that it's ready, but I'd have to investigate to know more.
The replicator doesn't let you use filtered changes yet.
Cheers
Jan
