iFood rebuilt its in-house security platform on ClickHouse Cloud, getting 9-16x faster queries at 40-50% of the cost and unlocking agentic threat hunts that cut a week of analyst work down to two hours.

This release brings speedups for GROUP BY ... ORDER BY ... LIMIT, three JOIN improvements, four vector search improvements, position-aware phrase search, EXPLAIN ANALYZE, unified URL access, and more!

You can choose any of these hundred database systems and run queries. You can create tables and databases, insert data, drop tables, etc. Every database comes with a preloaded dataset of 100 million records, so you can test example queries. It has not onl

We ran ClickHouse Managed Postgres and PlanetScale on the same hardware. ClickHouse delivered up to 54% higher throughput with lower latency.

ClickHouse has achieved the AWS Small and Medium Business Competency, joining a select group of AWS Partners recognized for deep expertise in real-time analytics for small and medium businesses.

This is a complicated post. So I need you to promise me something: if you read past this introduction, you’ll read the whole rest of the way through. It’s an honor thing. A couple months back, Theo Browne ran a video rating the “best place to host a

PostgresBench now includes HA benchmarks, comparing the performance of managed Postgres services under production-style HA configurations. This post explains the architectures behind each service and analyzes the trade-offs between availability guarantees

Recent improvements to the OpenTelemetry Collector's Datadog receiver let teams reroute telemetry from their existing Datadog agents and SDKs to ClickStack. or any OTel destination making migrations and evaluations simpler than ever.

This post shows a lightweight metrics layer for ClickHouse using MooseStack, an open source developer agent harness for ClickHouse.

ClickHouse 26.2 is here! In this post, text-index and QBit data type become production-ready.

How to remain competitive in the AI era of software engineering

Discover how Postgres managed by ClickHouse compares to its peers in a reproducible, open benchmark.

ClickHouse now brings full-text search and large-scale analytics together in one engine, making it a powerful alternative to Elasticsearch for log analytics. This benchmark shows why.

We use clickhousectl to spin up multiple ClickHouse versions side by side and benchmark two recent performance improvements.

ClickHouse 26.5 is here! In this release, we have a record number of performance optimizations, a new `filesystem` table function for querying your local file system with SQL, and more!

ClickHouse Cloud takes on Snowflake, Databricks, BigQuery, and Redshift on TPC-H, ranking first on SF100 cost-performance and running SF10 for less than one cent.

Over two years of focused join engineering, ClickHouse became 26× faster on the TPC-H SF100 join-heavy workload. Here’s how parallel hash joins, runtime filters, lazy column replication, and smarter join planning got us there.

Postgres managed by ClickHouse's first major update since public beta, covering fine-grained access control, a redesigned console, Terraform support, MCP integration, Stripe provisioning, migrations, billing, and capacity reservations — all shipped in und

Real-time analytics is more than fast queries. CostBench compares Snowflake and ClickHouse Cloud across the full path: continuous ingest, query-ready data maintenance, freshness, query latency, and cost.

We scaled our internal logging platform from 19 PiB to 431 PiB and 1.59 quadrillion rows. Here’s how we rearchitected LogHouse to handle 80 GiB/s of writes while keeping queries fast and the underlying complexity invisible.

chDB embeds a full ClickHouse query engine inside an agent's own process, turning data access, memory, and federation into local function calls instead of network round trips, cutting the latency, retries, and token waste that come with remote queries.
