-------------------------------------------
Summary: ddoc-based conflict resolution
Key: COUCHDB-1950
URL: https://issues.apache.org/jira/browse/COUCHDB-1950
Project: CouchDB
Issue Type: Improvement
Reporter: Nathan Vander Wilt
This was discussed at CouchConf in Vancouver last month, but didn't see a hook
here I could refer to in another conversation, so…
It'd be great if a design document could include a conflict resolver function,
in the vein of other "app logic" handler hooks like validate_doc_write. I
imagine it would look something like either "function (currentWinner,
nextWinningestLoser, parent)" (simply called multiple times if more than 2
leafs) or simply "function (arrayOfDocs, revisionHistor)" — if it returns a
document, that's the winner, if not the next design document in line gets a
pass at it. (Bonus: if it throws, the conflict stays no matter what other
resolvers say?)
