Hi, I have two machines, A and B. I am running an analysis on A, saving the output to couchdb, and then replicating by push from A to B.
B's database started life from this push replication, and has never been otherwise modified. So the two are more or less identical. What I want to do now is parallelize my work flow and run more analyses on B, save locally (to B's couchdb), and then replicate those changes to A. (The database is used both to save output, and also to keep track of what has been done already, so it is useful to keep the output db syncronized between all machines.) My question is whether replicating from B to A will require pushing all of the docs to A. This is an issue because my database is 21 GB and growing, and I'd rather not push all that data from B to A when I *know* the two are identical right now. Is there a way to set up replication to skip everything already there? Or to copy the replication state from A to B so that B knows that replication with A can start with new data only? If not, I can of course just save work done on B to the CouchDB on A directly, but I'd rather set it up so that the computation process always just hits couchdb on localhost, and let couchdb do the machine to machine copying. Thanks for any insights or pointers to the correct docs page, James Marca
