September 2026 newsletter
Blog post from ClickHouse
ClickHouse’s newsletter highlights the 26.8 release, which introduces custom HTTP handlers, dynamic query filtering, pipelined SQL transformations through the |> operator, a user-specific query log, a URL database engine, and Japanese and Chinese text-index tokenizers. It recognizes PostHog engineer Rory Shanks for contributions including replica mutation-data fetching, absent-token caching, and improved JSON subcolumn reads, while also covering technical resources on replication queues, query-plan analysis, and CostBench’s cloud data warehouse performance-per-dollar comparisons. The update announces private previews for On-Demand Compute, featuring dedicated workers, a cost-based optimizer, and distributed query execution, as well as PromQL support and a TimeSeries engine intended for Prometheus-compatible metrics workloads. It also reports expanded PostgreSQL initiatives, including WAL-based replication through WalShadow, Managed Postgres on Google Cloud, and a chdb PostgreSQL extension, alongside previews of AI SQL functions and other community projects. The newsletter concludes with a broad schedule of webinars, training sessions, Open House Roadshow stops, and industry events across the Americas, EMEA, and APAC.
