Redis Enterprise provides orders of magnitude higher performance than both Datastax and MongoDB, making the costs associated with scaling to high throughput and latency practically disappear when used instead of both those databases. With its unique Active-Active geographic distribution based on CRDTs, Redis Enterprise brings added advantages of:
-Simultaneous reads and writes to the same shared, distributed dataset with built-in smart conflict-resolution
-Assured local latencies regardless of the number of replicas associated with the dataset, since conflicts are handled in a consensus-free manner
-Assured availability regardless of how many other replicas are available (i.e. no need for quorum).
Add in the development simplicity and versatile data structures of Redis Enterprise, and the choice is even easier.
