ScaleOut Software integrates Redis open source software runtime capabilities into its Scaleout StateServer product


ScaleOut Software introduces support for Redis clients in ScaleOut StateServer version 5.11, available as a community preview.

With this release, Redis users can leverage the company’s flagship distributed caching product to connect to a cluster of ScaleOut servers and run Redis commands.

This open-source Redis software integration with ScaleOut StateServer adds breakthrough functionality for Redis users by dramatically simplifying cluster management, enabling seamless throughput scaling, and automating recovery from server and network failures. , according to the suppliers.

Aimed at enterprise users, ScaleOut StateServer now offers significant new features and the potential for substantial cost savings over competing commercial Redis products.

Redis clients can connect to a ScaleOut StateServer cluster the same way they connect to a Redis cluster and using the same RESP protocol.

This release implements all Redis data structures (strings, sets, sorted sets, lists, and hashes), as well as transactions, publish/subscribe commands, and utility commands.

This release does not include support for streams, modules, LUA scripts, and AOF persistence. Redis support integrates open source Redis version 6.2.5 code to process Redis commands, and offers the ability to run on Linux or Windows servers.

Unlike open source Redis, ScaleOut StateServer implements fully consistent updates to stored data. Additionally, ScaleOut StateServer’s native APIs run alongside Redis commands and incorporate advanced features, such as data-parallel computing, streaming analytics, and consistent and extensive data replication not available on open-source Redis clusters.

Key features include:

  • Current Open Source Redis Code: ScaleOut StateServer has integrated Redis version 6.2.5 into its software architecture to manage stored data as a single Redis database and to execute all Redis commands. The results produced by Redis commands are identical to those of an open source Redis server.
  • Significantly simplified and improved cluster management: ScaleOut StateServer automatically manages all cluster operations, including hashslot creation, load balancing, data replication, failure detection, and recovery. It distributes Redis hashslots across a cluster of servers and redistributes them as servers are added or removed. It also uses fully consistent cluster membership to detect server or network failures, rebalance workloads across surviving servers, and create additional replicas to maintain redundancy of stored data.
  • Advanced client management: ScaleOut StateServer simplifies client applications by always providing clients with accurate information about the location of hashslots. It automatically blocks client commands while hashslots are in motion to avoid client-side exceptions and ensure clients always see a transparent cluster view.
  • Multi-threaded architecture: ScaleOut StateServer’s multi-threaded architecture automatically uses all processing cores to speed up execution of Redis commands. This eliminates the single-threaded bottleneck created by Redis’ event loop architecture and avoids the complexity of deploying additional “shards” to increase throughput on each server.

“We are excited to provide a new runtime platform to Redis customers with ScaleOut StateServer to meet the needs of enterprise users,” said Dr. William Bain, CEO and Founder of ScaleOut Software. “By incorporating this technology, Redis users can take advantage of ScaleOut StateServer’s industry-leading cluster management capabilities to both reduce operational costs and achieve full consistency for stored data.
