ScaleOut In-Memory Database

What ScaleOut In-Memory Database is
ScaleOut In-Memory Database combines ScaleOut Software’s cluster architecture with Redis for enterprise Redis deployments. It runs self-hosted on Windows and Linux and provides API access. The product incorporates Redis 6.2.5 code and supports Redis structures, transactions, pub/sub, and the standard Redis client/server protocol. Supported data models include strings, lists, sets, hashes, sorted sets, streams, hyperloglogs, geospatial data, transactions, and pub/sub. Cluster management creates and distributes Redis hashslots, then migrates them as servers change or recover. Each hashslot has at least one replica on another node, with replicas redistributed as the cluster changes. Quorum-based updates are sequentially consistent by default, with eventual consistency available as an option. Multi-threaded command execution uses available processing cores. Standard RESP clients can connect, including StackExchange.Redis and Jedis. High availability is supported, but SQL is not. Lua scripting, Redis modules, AOF/RDB persistence, and other documented features are excluded from the noted release. Pricing is on request, with a 30-day trial and no free plan.
