Valkey
High-performance in-memory data store for secure stream messaging
Why Valkey?
Valkey is an open-source, high-performance in-memory data store — a community-driven fork of Redis. It is fully API-compatible with Redis, supporting the same protocol and commands, while being developed under the Linux Foundation with a permissive BSD license. Signando uses Valkey Streams for reliable inter-process communication between ALG components.
Signando + Valkey
- Stream Messaging — Inter-process communication via Valkey Streams (XADD/XREADGROUP).
- Redis Compatible — Drop-in replacement for Redis, same protocol and commands.
- mTLS Authentication — All Valkey connections use mutual TLS with per-lane ACLs.
- Consumer Groups — Reliable message delivery with acknowledgment tracking.
- Memory Safety — noeviction policy prevents silent data loss from stream eviction.
