A single misconfigured rate limit took down my Grafana dashboard during a Prometheus scrape storm. Here's the Traefik RateLimit middleware config that protects services without blocking legitimate traffic. View the complete homelab infrastructure source on GitHub 🐙 Grafana runs on k3s behind…
A long prompt costs more than compute time. It costs memory, and that memory is the KV cache. According to DeepSeek’s V4.1 announcement, its new architecture needs roughly one quarter of the previous generation’s HBM for the cache and one eighth…
How to move LLM calls out of request handlers and into a BullMQ queue: idempotent jobs, Retry-After aware backoff with jitter, worker rate limits, schema-validated model output and a dead-letter queue. Tested TypeScript code. Put LLM calls behind a BullMQ…
I benchmarked a hand-written SKIP LOCKED queue, pg-boss 12 and BullMQ 6 on both Redis and PostgreSQL: enqueue speed, throughput, pickup latency, crash recovery, transactional enqueue and storage per job. If your data is already in PostgreSQL and you run up to…
I measured PostgreSQL 18 LISTEN/NOTIFY against Redis 8 Pub/Sub for delivery latency, fan-out and the cost to the writing transaction, then checked rollbacks, payload limits and disconnects, with a tested Node.js SSE pattern. This is one machine with client…
PikVue - Smart Tech Tool Reviews In-memory databases are the backbone of real-time applications — session stores, caching layers, rate limiters, and leaderboard systems all depend on fast key-value storage. Redis has dominated this space for 15 years, but two challengers have emerged…
How often you can use the MCP server depends on your plan and seat. Per-minute limits apply in addition to daily or monthly limits. Education plans have the same limits as Full and Dev seats on the Professional plan: up…
This guide extends each model server's prefix cache beyond accelerator HBM: instead of discarding evicted KV blocks, the model servers offload them to CPU RAM and, optionally, a shared filesystem, and load them back when a follow-on request (a multi-turn…
KV stores, CDNs, edge runtimes, and latency-first data patterns.
