Grafana Mimir Storage: Tiered S3 at 10TB/day

Grafana Mimir storage at 10TB/day scale forces real trade-offs — here's how to configure tiered storage to S3 without bleeding cost or tanking query performance. You'll learn: • How Mimir's store-gateway and compactor interact with S3-backed object storage at high ingest volume • Configuring blocks_storage with tiered retention — keeping hot blocks in fast storage while offloading cold blocks to S3 Glacier-compatible tiers • Tuning compaction schedules and chunk caching (memcached) to reduce S3 GET costs under sustained 10TB/day ingest • Common pitfalls: misconfigured bucket lifecycle policies, compactor overlap errors, and index cache misses killing query latency • Sizing ruler and alertmanager storage separately so they don't contend with block storage I/O Keywords: Grafana Mimir S3 storage, Mimir tiered storage config, Mimir compactor tuning, metrics storage at scale, Mimir blocks_storage 🎧 Listen, then go deeper — DevOps & Cloud interview-prep ebooks at DevOpsInterview.Cloud (https://DevOpsInterview.Cloud/?utm_so...)
