Clickhouse
Postgres at Open House NYC
At ClickHouse Open House NYC, the team announced WalShadow, an open-source engine that replicates Postgres into ClickHouse from the physical WAL, achieving sub-second latency and high throughput. They also launched ClickHouse Managed Postgres on Google Cloud in private preview, offering Postgres on local NVMe storage with native CDC into ClickHouse. The chdb Postgres extension was released, enabling fast imports from cloud storage using the embeddable ClickHouse engine. A live demo showed WalShadow keeping ClickHouse under 400 ms behind during a simulated trading platform with 50,000 trades per second, and detecting a fraud burst in under 500 ms compared to over 15 seconds with ClickPipes. The integrated stack aims to provide world-class Postgres for transactions and ClickHouse for analytics, with WalShadow as a key step toward unifying OLTP and OLAP.

How Fountain rebuilt its data plane on ClickHouse Cloud to power Cue, the Frontline Superintelligence
Fountain rebuilt its data plane on ClickHouse Cloud to power Cue, its agentic AI platform for frontline hiring, moving off a multi-vendor BigQuery and S3/Iceberg batch stack. The migration cut analytics latency from three hours to under two minutes, with most queries returning in under a second, at roughly 66% lower cost. Data from 13 Postgres production databases and four MongoDB databases streams into ClickHouse Cloud via ClickPipes managed CDC, landing as Iceberg and Parquet in S3 before reaching BigQuery and ClickHouse. The new architecture uses two symmetrical pipelines—one for Postgres, one for MongoDB—each running a short path: source, ClickPipes, materialized views, and Cue. The system now carries 8.48 billion CDC rows replicated continuously by ClickPipes and 10.3 billion analytics rows across 15 deployments, served by over 2,000 incremental materialized views.

The best engineering reads, once a week.
