Document revision

[devlist]

Not really a mobile question, but we need to find out what is going wrong with Couchbase 5.
The new release means we can update documents in the bucket without needing a shadow bucket.

Couchbase 5.0.0 or 5.0.1
Bucket with no Sync Gateway.
Create a new document via REST or web GUI and the CB revision is NOT 1. It could be 5 or 473 for example.
This is without XDCR enabled.

I suspect what is happening is that the document is created with rev 1, but then it’s internally updated multiple times for some reason.
I think this because if XDCR is enabled the copy created on the other CB server has rev 1 !

This weird behaviour totally messes up XDCR as this sequence occurs…

Create a new doc on Server A, rev is 5.
XDCR doc appears on Server B, rev is 1.
Update or delete doc on Server B rev is 2.
Rev 2 is lower than 5 so doc is never synced and doc on Server A is stale.
Update or delete doc on Server A rev is 6.
XDCR doc appears on Server B, rev is 6.


If we remove manually all the documents the behaviour stays broken.
If we purge the bucket then add a document the revision ID is 1.
But then after a while this fault returns.

Any one using CB 5 ?

In Couchbase is there a way to show revision history (like there is in CBL)

Thanks,

Martin

Interesting.  Would you mind posting to https://forums.couchbase.com/ and tagging it w/ XDCR?

I have some ideas on what might be happening, but I think the conversation is much better to have in forums.couchbase.com since the engineers that work on Couchbase Server + XDCR follow that forum (but not this one, which is mobile-only)
