CouchDB Replication

Questions

Is it possible to set order for database replication? http://stackoverflow.com/questions/15285520/couchdb-is-it-possible-to-control-order-of-replication

Examples

curl -X POST -H "Content-Type:application/json" http://localhost:5984/_replicate -d '{"source":"http://isaacs.iriscouch.com/registry/", "target":"registry"}'

curl -X POST 'http://localhost:5984/_replicate' -H 'Content-Type: application/json' -d '{"doc_ids": [ "coffee-script", "nodeunit", "npm" ], "source": "http://registry.npmjs.org:5984/registry", "target": "registry", "create_target": true}


curl -X POST http://localhost:5984/_replicate -d '{"source":"http://isaacs.iriscouch.com/registry/", "target":"registry"}' -H "Content-Type:application/json"

Successful:

curl -X PUT http://localhost:5984/registry01
curl -X POST http://localhost:5984/_replicate -d '{"source":"http://isaacs.iriscouch.com/registry/", "target":"registry01"}' -H "Content-Type:application/json"

Replicate only desired packages

$ curl -X POST -H "Content-Type:application/json" http://localhost:5984/_replicate -d '{"source":"http://isaacs.iriscouch.com/registry/", "target":"repo1", "doc_ids":["0"]}'
