We added a gamma scalping signal to the #QuestDB cookbook. It builds a realized vol to spread ratio in SQL to estimate when rebalancing can cover transaction costs. High ratio helps, but not enough. You still need to overcome theta decay. Details in thread 👇

We often get questions about high availability in #QuestDB. We added new architecture diagrams to show how it works: WAL replication through object storage, automatic primary failover, and multi-region replicas serving concurrent queries. Details in thread 👇

We introduced HORIZON JOIN in #QuestDB. ASOF JOIN gives a point-in-time match. WINDOW JOIN aggregates over a time range. HORIZON JOIN returns results at multiple time offsets before or after each row, letting you build curves that show how values evolve around events.

Agentic AI is changing how software gets built. Here an agent installs #QuestDB, ingests crypto orderbook data, and runs OHLC queries in seconds. Open standards like SQL, REST, and Parquet make it easy for agents to explore systems and generate working code quickly.
