CouchDB _rev conflict issue while updating bulk documents

Question

I am trying to update bulk documents using nano couch package from npm (https://www.npmjs.com/package/nano) but sometimes due to different _rev for same document , couch is skipping the update for those documents . But in my case i want to update all the documents irrespective of _rev value

So i tried using new_edits: false which will ignore _rev value and force update all the docs , but in my case couch is skipping all the docs if i use new_edits: false it is not even updating single doc when i use that flag

below is my code snippet

await db.bulk({ docs: conf['docs'] , new_edits: false }).then(body => {
numberOfUpdates = body;
});

Is there any other way to update documents irrespective of _rev value using nano couch package

Answer 1

Just Before making bulk save documents in couchdb, you need to:

1. Fetch all the documents with _ids that you need to bulk save.
2. Replace _rev from documents fetched from the db in #1 to the documents that you want to save in the db
3. Now make bulk save call to the db

The above steps will ensure that when you make a bulk save call, you are passing the latest _rev which will avoid the Document Update Conflict(s).
