ClickHouse December 2025: Postgres Integration, Performance Gains, and Cost-Performance Insights

ClickHouse: The Future of Analytics?

The December 2025 ClickHouse newsletter offers a comprehensive look at the platform's evolution. The introduction of the pg_clickhouse extension is particularly noteworthy, bridging the gap between Postgres users and ClickHouse's analytical capabilities. The cost-performance analysis comparing cloud data warehouses provides valuable insights for users seeking to optimize their spending. The year-in-review of Postgres CDC showcases the project's maturity and growing adoption. However, the newsletter's focus is primarily on existing features and improvements, rather than groundbreaking innovations. While the content is valuable, it lacks a clear articulation of a long-term strategic vision.

One potential limitation is the reliance on existing integrations. While the Postgres extension is beneficial, it also assumes users are already invested in the Postgres ecosystem. Furthermore, the newsletter's coverage of various topics, while comprehensive, might make it challenging for readers to prioritize which advancements are most critical for their use cases. Providing a more curated view based on user personas, or highlighting the most impactful features for specific roles, could enhance the newsletter's utility. The emphasis on training and certification is a positive sign of community building, but it also reflects a need for more widespread adoption and understanding of ClickHouse's capabilities.

Key Points

• pg_clickhouse extension released, enabling Postgres users to query ClickHouse directly.
• Cost-performance analysis provides insights into cloud data warehouse pricing.
• Improved performance in 25.11 release, including faster GROUP BY operations and new functions.
