A fair emphasis on what differentiates RavenDB from CouchDB (nb coming from RavenDB creator). Just to mention the most interesting ones:
- transactions: support for single document, document batch, multi request, multi node transactions […]
- set based operations:
update active = false where last_login < '2010-10-01'
- includes and live projections (local data only)
