Satellite Collections (Enterprise Edition only) is a great new feature where you can instruct the engine to use replicas for processing, removing the need for a network hop to find key collection data on another node. Key for many serious Enterprise customers like Banks and Governments. The Enterprise version also benefits from LDAP security support, and encryption at rest. Certain graph algorithms demand running on a single machine with all the data, so being able to choose should keep graph aficionados happy! Interestingly, you can choose single node or cluster execution. Think of this like an efficient version of Map/Reduce for graph algorithms processed across data spread throughout the cluster. Support for the Pregel graph processing model will be a boon for developers. This should greatly improve performance under high write and read loads. It’s a positive change though, allowing document-level locking, and preventing writes blocking reads, and vice versa. Plus, as MongoDB customer found out when introducing WiredTiger as a storage engine, you’ll always want to test and retest a new storage layer to look for unanticipated regression and performance issues. This is a huge change that will require load testing in your applications, as consistency and locking work differently than the previous mmfiles method. The biggest change is the use of Facebook’s RocksDB key-value store as a storage engine (I’ll review RocksDB separately in a future article).
