MongoDB Adapter for ProophEventStore, _(*2)

CAUTION: The mongoDB adapter is NOT compatible With prooph/event-store v7. MongoDB has limited ACID support which is not compatible with the new features of prooph/event-store. MongoDB is a great choice for a read model database, but unfortunately it cannot be used as an event-store that requires transactions across documents (events).

Codeliner has published a Gist that shows a custom implementation of a possible mongoDB event store supporting a subset of the v7 features in a very limited way. If you want to try to bring mongoDB back, please get in touch with us and we can discuss it!, _(*3)

Support for the adapter will end at 31 December 2017., _(*4)

Requirements

• MongoDB >= 4.0
• MongoDB PHP Driver >= 1.5.2

Transactions

The transaction write concern for this adapter is majority., _(*5)

The transaction read concern for this adapter is snapshot., _(*6)

You can disable transactions for this adapter., _(*7)

Considerations

This adapter does not use the MongoDB ObjectId for its primary key, instead a UUID (string) is used., _(*8)

We recommend the AggregateStreamStrategy as the best strategy to use with this adapter., _(*9)

Keep in mind that transaction safety works only for a replica set. Sharded cluster support is planned for MongoDB 4.2. Therefore it's not safe to use this adapter in a sharded cluster environment, as MongoDB can't guarantee transaction safety., _(*10)

Stream can not be reset if iteration was started due the MongoDB cursor., _(*11)
