WalShadow is now available in private preview for ClickHouse Managed Postgres. It allows users to test replication latency, verify data correctness, and manage schema changes and recovery processes.
The MongoDB CDC connector for ClickPipes is now generally available. It supports parallel snapshotting, structured ingestion into typed columns, and provides lag and resource metrics.
The September and October ClickStack updates add ad hoc dashboard filters, PromQL support across all chart types, query tracing, a Trace logs tab, and chart explorer alerts.
Version 0.5.0 of clickhousectl adds Cloud support for UDFs, observability for ClickHouse Managed Postgres, and standardized command permissions.
ClickHouse released a cost-based join optimizer that automatically reorders inner, outer, semi, and anti joins to determine the most efficient execution plan.
ClickHouse Managed Postgres now provides notifications for inactive replication slots, planned switchovers, unplanned failovers, long-running transactions, and connections approaching their limit.
Users can now connect Cursor to Langfuse to trace agent turns and analyze model and tool calls, with ClickHouse providing the underlying analytics infrastructure.
Query Insights for ClickHouse Managed Postgres now includes wait event breakdowns, blocked-session charts, and lock-wait charts. These metrics are also available in Prometheus.
ClickHouse released a native TCP client for .NET, offering faster reads and inserts with lower memory allocations. The client supports columnar APIs, POCO mappings, and provides a migration path from HTTP.
Managed ClickStack now includes built-in z-score anomaly detection to highlight unusual chart values. A faster, sharded alert scheduler allows teams to migrate tens of thousands of alerts from external monitoring tools.
ClickHouse Cloud now supports JWT authentication, enabling database connections to authenticate using short-lived tokens from an identity provider rather than standard database passwords.
Executable User-Defined Functions (UDFs) are now generally available on ClickHouse Cloud across AWS, GCP, and Azure, featuring native runtimes, network access, observability, and API and Terraform support.
ClickHouse Cloud now supports SCIM 2.0 for automated user and group management. This allows identity providers to synchronize member creation, updates, and role assignments directly to ClickHouse.
ClickHouse Workload for Microsoft Fabric is now in public preview, enabling sub-second analytics on OneLake data. It provides dedicated compute for dashboards, agents, and applications.
ClickHouse introduced the chDB Durable Layer, which keeps agent memory fast to query locally while making its analytical state recoverable across environments.
ClickHouse 26.9 introduces conditional LIMIT boundaries, incremental refreshes for append-only materialized views, disk spilling for DISTINCT queries, time-limited tokens, and query optimizations for min, max, and count operations.
The official ClickHouse provider for Apache Airflow simplifies data workflows with standard SQL operators, bulk inserts, and shared setup across self-managed Airflow and Astronomer.
The ClickHouse adapter for dbt v2 is in public beta, powered by dbt’s Rust engine. ClickHouse also joins the dbt platform in private beta, supporting open-source ClickHouse and ClickHouse Cloud.
Temporary tables and named sessions live on a single ClickHouse replica, so a follow-up query routed elsewhere can't see them. Replica-aware routing pins your requests to the same replica over HTTP or the native protocol , and here's how we built it.
ClickHouse On-Demand Compute lets you scale individual queries with additional workers, run intensive workloads without disrupting production, and use compute when you need it.
ClickHouse Managed Postgres is expanding to Google Cloud, bringing NVMe-backed storage, native CDC into ClickHouse, and a unified query layer via pg_clickhouse to GCP private preview customers.
The chdb Postgres extension brings fast imports and exports across cloud storage platforms and data formats, powered by the embedded ClickHouse engine.
ClickHouse Managed Postgres now supports scheduled upgrade windows, giving Scale and Enterprise users more control over when routine platform maintenance occurs.
Replicate MySQL and MariaDB data into ClickHouse Cloud with the generally available MySQL CDC connector, featuring faster parallel snapshots, safer production defaults, improved observability, and infrastructure-as-code support.
See how a four-step onboarding flow helps users move from provisioning ClickHouse Managed Postgres to querying operational data and running real-time analytics with ClickHouse.
Discover how ClickHouse .NET Driver 1.1–1.3 adds type-safe POCO workflows, extensible serialization, broader type support, performance improvements, and official ecosystem integrations.
The ClickHouse Terraform provider now manages ClickStack dashboards, alerts, sources, and webhooks, putting observability config in version control.
ClickStack and Hud now share trace IDs, pairing service-level observability with function-level runtime forensics so coding agents can assess risky changes before they ship, catch regressions right after deploy, and fix them with real production context.
Discover what's new in pg_clickhouse v0.10.0: 16 of 22 TPC-H queries now push down in full, plus a rebuilt C driver and broader aggregate support.
Explore ClickStack’s latest upgrades, from richer trace navigation and Prometheus connectivity to smarter dashboards, quieter alerts, faster filtering and support for exponential histogram metrics.
Explore the latest ClickHouse Managed Postgres updates, including proactive notifications, richer observability, faster backups, and expanded extension support.
clickhousectl v0.4.0 adds horizontal autoscaling for Cloud services, ClickPipe schema discovery, finer control over ClickPipe ingestion, and opt-out anonymous usage telemetry.
We have relaunched clickhouse.com/docs on Mintlify, with a redesigned search and Ask AI experience, a docs MCP server, simpler navigation, an interactive API playground, and expanded localization , built for both human readers and the coding agents
We've released @clickhouse/rowbinary a Node.js reader and writer for ClickHouse's RowBinary formats. You can import it and call its generic parser like any other library. But it also ships as an Agent Skill: point a coding agent at the bundled `SKILL.md`
ClickHouse is now available as a Docker Hardened Image: a minimal, security-hardened build that passes enterprise vulnerability scans by shipping only what the database needs to run, with no change to how ClickHouse behaves.
Introducing pg_re2, a Postgres extension that brings ClickHouse's fast RE2-powered regular expressions to Postgres, with benchmarks and pg_clickhouse pushdown integration.
ClickStack can now generate full dashboards and linked investigative workflows from a single prompt, using an AI Notebook and the same MCP tools available to external agents like Claude, Cursor, and Codex.
ClickHouse 26.6 is here! In this release, we have hypothetical skip indexes, cascading refreshable materialized views, experimental support for continuous queries, and more!
ClickHouse Agents now connects directly to Managed Postgres, so you can query your operational data in plain English, combine it with ClickHouse in a single request, and get agent-guided help monitoring, tuning, and migrating your databases.
Silk is a new open-source C++ fiber runtime built for ClickHouse, combining a NUMA-aware work-stealing scheduler, io_uring I/O, and zero heap allocation in the steady state to deliver nanosecond-level fiber yields and dramatically lower tail latency for h
Announcing the Managed ClickStack MCP Server: purpose-built observability tools, full-fidelity telemetry, and dedicated compute for AI-driven investigations at scale.
