Memstate is a complete redesign of OrigoDB with major improvements in key areas such as performance, availability, licensing, cross-platform, docker and cloud support.
Performance - OrigoDB can process up to 3K write transactions per second, Memstate can process up to 100K, a 33x improvement!
High Availability - An OrigoDB cluster has a single primary and one or more read-only replicas. If the primary fails one of the replicas can be promoted to new primary but this requires manual intervention. Nodes in a Memstate cluster are all read/write.
Licensing - OrigoDB Server is a commercial offering while Memstate server is OSS and free for commercial use.
Cross platform - Memstate targets .NET Standard 2.0 which means it runs on both .NET Framework >= 4.6.1 and .NET Core >=2.0, Mono, Xamarin, UWP.
