Playing around with MongoDB and NoRM in .NET.
Thing that confused me - there are no transactions
(can't just tell MongoConnection.Begin/EndTransaction or something like that).
I want to use Unit of work pattern and rollback changes in case something fails.
Is there still a clean way how to enrich my repository with ITransaction?
MongoDB doesn't support complex multi-document transactions. If that is something you absolutely need it probably isn't a great fit for you.
In most cases, however, we've found that complex transactions aren't a requirement. All operations in MongoDB are atomic on a single document, and we support nice update modifiers, which make a lot of operations that would need a transaction easy to implement (and fast).
