A diagnostic guide to gRPC health check failures: matching symptoms like UNAVAILABLE errors and false NOT_SERVING statuses to transport, naming, and deadline causes, with ordered checks and fixes.
Learn how to declare a retryPolicy in a gRPC service config so unary RPCs automatically retry on transient errors like UNAVAILABLE while respecting idempotency and deadlines.
Local rate limits silently scale with your replica count. Envoy's global rate limiting centralizes quota decisions in an external gRPC service — here's how the pieces fit, a working per-IP example, and the fail-open vs. fail-closed decision you can't skip.
Guidance on requirements, minimal design, trust boundaries, operational checks, failure modes, and redesign triggers for SpiceDB's Watch API.
Learn how gRPC bidirectional streaming lets clients and servers exchange messages over a single HTTP/2 connection, with a concrete chat‑service example, trade‑offs, and verification steps.
gRPC deadlines and cancellation travel with the RPC via context propagation, letting servers abandon work the moment the caller stops waiting. Here's how to wire it up correctly — and where it silently fails.
A diagnostic guide for resolving Teleport connectivity and authentication failures between the Proxy and Auth Service, focusing on TLS, ports, and gRPC errors.
Client-side load balancing in gRPC lets clients discover back-ends and distribute traffic without a separate load balancer. Start with round-robin and DNS or Kubernetes discovery, then verify with connection tracing and distribution checks.
Guide to decide when to use strong (FULL) or eventual (ZONKED) consistency for permission checks in SpiceDB, with trade‑offs and a validation example.
