Subject MVCC and update locking
Date Thu, 18 Aug 2011 17:49:25 GMT

CouchDB claims to be lockless, thanks to its use of MVCC. Both CouchDB and
MarkLogic claim to use MVCC.

However, states
that MarkLogic does read and write locking for updates.

Does CouchDB also do the same ? If not, how does it do updates differently ?
