Blog post from ClickHouse
The January 2026 ClickHouse newsletter highlights several advancements and community contributions in the ClickHouse ecosystem. It covers the zero-copy integration of chDB with Pandas DataFrames, significantly improving query performance by enabling direct memory sharing between ClickHouse and NumPy. WKRP's migration from TimescaleDB to ClickHouse for their RuneScape tracking plugin resulted in substantial storage efficiency and operational simplification. The newsletter also emphasizes the versatility of ClickHouse through various case studies, including solving Advent of Code 2025 challenges using only ClickHouse SQL and replacing Apache Flink with ClickHouse's Kafka engine for real-time data streaming. Additionally, the newsletter features contributions from community member lgbo, who made several performance improvements, and outlines a series of upcoming events and workshops to engage with the ClickHouse community.
