Redis Labs Enterprise Cluster (RLEC)

Redis Labs Enterprise Cluster (RLEC) is available on Flash with the same blazing fast sub-millisecond latencies attained when running Redis on RAM. The breakthrough technology behind this product uses Flash as RAM extension, rather than as persistent storage. The global key list and all ‘hot’ values are kept in RAM, while all ‘cold’ values (which typically account for the larger part of the dataset) are kept in Flash. Multi-threaded and asynchronous Redis is used when accessing objects on Flash, utilizing a multi-core and Flash concurrency architecture. The product is fully compatible with all Redis clients, data types and commands.

RLEC Flash is extremely suitable for use cases in which values are significantly larger than the keys and where "hot" objects account for 10-40% of all objects.

In many cases, RLEC Flash can save up to 70% in resource costs as compared with an all-RAM deployment.

The ratio of RAM to Flash can be easily set by the user in order to optimize performance to your specific use case.

RLEC Flash characteristics and features are identical to those of standard RLEC. The product is available in an x86/ 64-bit version and a POWER version (as part of the IBM NoSQL Data Engine).
