Why Meridian

Everything your Trino platform is missing

⚡

Warm Pool

Pre-warmed clusters sit idle and are claimed instantly. No 30–90 second provisioning delay when a job needs a cluster.

🤖

MCP Server

19 tools for Claude, Cursor, and any MCP client. Reserve clusters, add catalogs, run queries — all through natural language.

☸️

Kubernetes Native

Three controllers, three CRDs. Runs in any Kubernetes cluster. No external dependencies, no database, no sidecar.

🔄

Dynamic Catalogs

Add and remove catalogs at runtime via Trino's catalog.management=dynamic. No cluster restart.

📈

Auto-scaling

ClusterPoolAutoscaler watches reservation utilization and scales the pool up or down automatically with hysteresis.

🔒

Idempotent Reservations

Same clientId + reservationId always returns the same cluster. Optimistic concurrency handles races safely.
