Welcome to KalamDB
KalamDB is a SQL-first realtime database designed for high-concurrency app workloads and agent systems.
It combines:
- SQL query and DDL workflows
- user-isolated and shared table models
- live query subscriptions over WebSocket
- topic consume/ack worker patterns
- vector search with
EMBEDDING(n)columns and cosine ranking - hot + cold storage lifecycle in one runtime
