ClickHouse as Postgres analytics sidecar

This move is less about turning ClickHouse into a true all in one database, and more about making ClickHouse the analytics brain that sits next to the system where the app already writes data. The product setup is concrete. A team keeps using Postgres for inserts, updates, and row level transactions, then streams those changes into ClickHouse through native CDC, so dashboards, product analytics, and AI monitoring stay fresh without stitching together separate vendors by hand.

• Ubicloud gives ClickHouse a fast path into managed Postgres without building that control plane from scratch. The service uses Ubicloud Postgres and control plane software, with local NVMe backed Postgres and a private preview launch in January 2026.

• This fits ClickHouse's broader upstream push. After acquiring PeerDB in July 2024, ClickHouse folded Postgres CDC into ClickPipes, and by late 2025 more than 400 companies were replicating over 200 TB of Postgres data into ClickHouse each month.

• The key competitive comparison is with databases like SingleStore and Firebolt that sell one engine for both transactional and analytical work. ClickHouse is taking a different route, pairing best of breed Postgres with best of breed analytics, which lowers adoption friction but still preserves a two engine architecture underneath.

This points toward a bundled data stack where ClickHouse wins more application adjacent workloads, especially AI products and user facing software that need fast writes in Postgres and fast reads in ClickHouse. The likely end state is not one universal database, but a tighter default pairing where ClickHouse becomes the standard analytical sidecar to Postgres.
