ClickHouse's raw performance with the ubiquitous compatibility of Postgres.
ClickHouse is helping us simplify a bold Customer Data Platform architecture by leveraging Postgres as a universal interface.
With pg_clickhouse, ClickHouse becomes a plug-and-play database for virtually any third-party tool (...) It's the best of both worlds.
Multi-terabyte workloads moved, without the operational complexity we expected.
We moved multiple multi-terabyte workloads from RDS and Aurora to ClickHouse Postgres with hands-on support from the ClickHouse team.
Given the scale and complexity of our cybersecurity data sources, reliability and price-performance were critical (...) The team has been a great partner across several complex deployments.
Why ClickHouse Managed Postgres?
NVMe performance
Enterprise-grade Postgres on local NVMe storage, delivering ultra-low disk latency and up to 10× faster performance for I/O-heavy workloads, without EBS throttling or network jitter.
ClickHouse integration
Unify transactional and analytical workloads with native CDC from Postgres to ClickHouse, fast replication, and pg_clickhouse for querying across both systems from a single layer.
Enterprise-grade Postgres
Postgres built for mission-critical workloads with high availability, automatic backups, point-in-time recovery, end-to-end encryption, private networking, and infrastructure powered by Ubicloud.
Open-source first
Build on an open-source stack with Postgres for transactions, ClickHouse for analytics, PeerDB for CDC, and pg_clickhouse as a unified query layer — with no vendor lock-in and full control of your data.
Unified data stack
Combine Postgres for transactions with ClickHouse for analytics to deliver best-in-class performance and scalability with minimal operational overhead.
NVMe-backed Postgres for OLTP
Unlock up to 10× faster Postgres performance with NVMe storage built for I/O-intensive workloads. Microsecond-level latency and millions of IOPS eliminate disk bottlenecks for high-throughput transactional applications.
Unlike traditional SSDs that cap out at a few hundred thousand IOPS, NVMe scales effortlessly, delivering lower tail latencies and faster system operations like VACUUM, checkpoints, and logical replication.
High availability is built in by design, with up to two dedicated standby instances reserved exclusively for HA. Read replicas are offered separately to preserve reliability. Automatic backups and point-in-time recovery (PITR) with WAL archiving ensure robust disaster recovery.
Blazing-fast replication
Replicate Postgres data to ClickHouse in real time to unlock up to 100× faster analytics. With replication latency as low as a few seconds, your data is analytics-ready almost immediately.
The pipeline supports both initial snapshots for existing datasets and CDC-based incremental updates. It’s powered by the ClickPipes Postgres CDC connector, proven in production by hundreds of enterprises moving hundreds of terabytes per month.
Coming next: more native CDC capabilities, including sub-second replication latency, reliable slot flushing through ongoing transaction replication, and other enhancements, exclusive to ClickHouse Managed Postgres.
Unified query layer
Query ClickHouse directly from Postgres using the pg_clickhouse extension. No proxies, no new query layer to manage. Postgres becomes a single interface for both transactions and analytics.
Queries are transparently pushed down to ClickHouse for maximum performance, supporting joins, filters, aggregations, and functions. Today, 14 of 22 TPC-H queries are fully pushed down, delivering 60×+ speedups.
Pushdown support continues to expand to CTEs, window functions, and more, enabling fast analytics from the Postgres layer while ClickHouse handles execution behind the scenes.
