ScaleOut In-Memory Database
ScaleOut In-Memory Database combines ScaleOut’s cluster architecture with Redis for enterprise Redis deployments.
What ScaleOut In-Memory Database is
ScaleOut In-Memory Database combines ScaleOut’s cluster architecture with Redis for enterprise Redis deployments. It runs self-hosted on Windows or Linux and provides API access. The product incorporates Redis 6.2.5 code, supporting Redis data structures, transactions, pub/sub, and the standard Redis client/server protocol. Supported models include strings, lists, sets, hashes, sorted sets, streams, hyperloglogs, geospatial data, transactions, and pub/sub. It automatically creates and distributes Redis hashslots, then migrates them as servers change or recover from failures. 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, while eventual consistency is optional. 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. Pricing is on request, with a 30-day trial and no free plan.
