If I have multiple instances of couch in a cluster with the same db should I  
register a river against each for the same db? Is it safe to do this?

Thanks

Multiple rivers pointing to the same elasticsearch index, then operations will be duplicated, I think, no? The question if its safe or not is really up to your app, elasticsearch will apply all the \_changes coming from couch into it the respective configured index.
