Valkey

What It Does

Valkey (Redis-compatible) serves as the shared in-cluster cache:

Usage	Description
L2 credential cache	Cached cloud credentials shared across pods
A2A task state	Task status and results for agent-to-agent communication
Tool registry	Cached tool definitions from the Gateway
Rate limiting	Per-tenant and per-agent rate limit counters

Why Valkey

Valkey is the open-source fork of Redis (post-license change). It is:

100% Redis protocol compatible
Apache 2.0 licensed
Drop-in replacement with no code changes
