Ben: 1.2 TiB is too much. Cut both stores to 3d and resize honestly. - NATS LOGS stream max_age 168h -> 72h in the nats-stream-limits ConfigMap. At the stated ~33 GiB/day compressed (S2), 3d ~= 100 GiB, so max_bytes -> 130 GiB and the file-store PVC -> 180Gi/node. 3 replicas = ~0.5 TiB total (down from 1.2 TiB). - ClickHouse logs.raw TTL 30d -> 3d in the bootstrap DDL. At ~130 GiB/day raw, LZ4/ZSTD (~6x) stores ~20-25 GiB/day => ~60-75 GiB/3d; with merge headroom the CHI PVC -> 150Gi (from 200Gi). logs.raw is the only table. - Long-term retention now lives EXCLUSIVELY in the S3 archive (logarchiver) for the configured subjects; everything else is gone after 3 days — accepted design, documented in the runbook + PR body. - Update all 7d/30d comments and the replay window (now 3d). PVC shrink is a plan-time change: this stack is not deployed yet, so it is clean. Once deployed, PVCs cannot shrink in place (would need recreate).
