When will my Valkey or Redis cache run out of memory? Sizing it with the Cache Size Simulator

used_memory tells you where you are, not where you're going. The Cache Size Simulator samples what your keys actually weigh, projects growth and TTLs forward, tells you when you hit maxmemory and what your eviction policy will do about it, and picks the smallest ElastiCache, MemoryDB, Memorystore or Azure node that still fits in six months. Works on Valkey, Redis OSS and other RESP-compatible databases.

OpenAI runs Valkey for a billion users. Here's how to run yours better.

OpenAI runs Valkey as the cache behind a billion ChatGPT users. You won't build Habitat with two engineers and Codex - but if you run the same cache, here's how BetterDB makes operating it better: persisted slowlog and latency, hot-key and connection-storm detection, ACL auditing, and CVE scanning.

OpenTelemetry, both directions: the monitor speaks OTLP in and out

The monitor now speaks OpenTelemetry in both directions: it re-emits its whole Prometheus surface and its events over OTLP, and its /v1/traces endpoint ingests OTLP spans from any instrumented service. That gives BetterDB four positions in your pipeline - feed your collector, be one, produce spans, or consume them and add the one thing a pure trace tool can't: the live database state behind the span. It fits wherever your stack has an OTLP-shaped socket open.

What shipped in July: offline licensing, native OpenTelemetry, and fifteen new detectors

A full month in review. BetterDB Monitor now runs fully air-gapped, speaks OpenTelemetry natively, grew its MCP surface, and picked up fifteen new anomaly detectors built straight from the Valkey issue tracker - plus cleaner migration off KeyDB and older Redis, and a month of caching and agent-memory SDK work.

No Internet Required: Air-Gapped Monitoring for Valkey and Redis

The teams that most need deep database observability are often the ones that can't send a single packet to the outside world. BetterDB Monitor 0.28.0 runs fully air-gapped: signed licenses, local verification, zero phone-home. This post covers how it works and the honest trade-offs.

You can't debug what you can't see: shipping the Vector / AI tab for valkey-search and RediSearch

Why FT.INFO and INFO commandstats aren't enough for production vector workloads on Valkey or Redis - and how BetterDB's new Vector / AI tab closes the gap.
