Unleash the Power of Configurable, Distributed In-Memory Storage

EchoVault is a highly configurable, distributed, in-memory data store and cache implemented in Go. It can be imported as a Go library or run as an independent service.

EchoVault aims to provide a rich set of data structures and functions for manipulating data in memory. These data structures include, but are not limited to: Lists, Sets, Sorted Sets, Hashes, and much more to come soon.

EchoVault provides a persistence layer for increased reliability. Both Append-Only files and snapshots can be used to persist data in the disk for recovery in case of unexpected shutdowns.

Replication is a core feature of EchoVault and is implemented using the RAFT algorithm, allowing you to create a fault-tolerant cluster of EchoVault nodes to improve reliability. If you do not need a replication cluster, you can always run EchoVault in standalone mode and have a fully capable single node.

EchoVault aims to not only be a server but to be importable to existing projects to enhance them with EchoVault features, this capability is always being worked on and improved.

Features

Some key features offered by EchoVault include:

  • TLS and mTLS support for multiple server and client RootCAs.
  • Replication cluster support using the RAFT algorithm.
  • ACL Layer for user Authentication and Authorization.
  • Distributed Pub/Sub functionality with consumer groups.
  • Sets, Sorted Sets, Hashes, Lists and more.
  • Persistence layer with Snapshots and Append-Only files.
  • Key Eviction Policies.
