March 2026 newsletter

The March 2026 ClickHouse newsletter highlights several developments, including the introduction of chDB 4, a Pandas-compatible DataStore API that operates on ClickHouse's engine, and the general availability of full-text search that utilizes inverted indexes for efficient token-based filtering. The newsletter showcases the work of community member Jamie Herre from Cloudflare, who presented strategies for managing both growth and failures in analytics infrastructure. Additionally, the newsletter covers Hookdeck's improvements in payload search speed, reducing query latency to under 400ms by implementing typed bucket columns and iterative time-window scanning. The Agentic Data Stack is introduced, offering a system where AI agents can query ClickHouse using natural language, and ClickHouse TTL strategies are discussed for efficient data retention and disk optimization. Upcoming events and training sessions across the globe are also detailed, providing opportunities for users to engage with the ClickHouse community and enhance their skills.
