ClickHouse Managed Postgres uses WAL-aware backpressure to prevent a WAL backlog from filling the disk and triggering a PANIC. clickhouse.com/blog/wal-bac... Client writes slow while the archiver drains at full speed. When the backlog clears, the cap lifts automatically.

clickhouse.comWhat is WAL backpressure, and why does ClickHouse Managed Postgres need it? | ClickHouseHow ClickHouse Managed Postgres uses WAL-aware backpressure to slow client writes, protect disk space, and let the archiver recover.

We're building Click-a-thon with some incredible companies. InMobi. Atlys. Sony LIV. These teams are bringing real-world engineering problems to the table, and 150+ developers will spend 24 hours building open-source solutions around them. That's what co-innovation looks like. 🧵 👇️

What 10 years of building in the open has produced: - 200+ integrations - Supporting open standards: OpenTelemetry, MCP, Iceberg, Delta Lake - dbt, Airflow, Grafana, Fivetran, PeerDB, and hundreds more - ClickStack, Langfuse, LibreChat building on top of ClickHouse clickhou.se/4ebNji0

clickhouse.comThe open ecosystem around ClickHouseAround any good database sits the clients you import, the dashboards your team shares, the pipelines that feed it, the projects that build on top of it, and now the agents that query it.

How do you monitor an SLA on a user-facing dashboard query? Tag queries with log_comment='frontend-dashboard'. Track p99 in system.query_log. When it breaches: concurrency problem → add replicas. Data growth → bigger replicas. clickhousectl lets an agent drive the whole loop. clickhou.se/4e7atF6

clickhouse.comMonitor SLAs and scale ClickHouse Cloud with clickhousectl and agentsTag queries to track per-workload SLAs, then use clickhousectl to investigate breaches and scale ClickHouse Cloud, with an agent to remediate.

India's devs are building some of the most data-intensive systems on the planet. We want you in the room, building something real. What will you build? Click-a-thon 2026 is ClickHouse's first in-person hackathon in India. Bengaluru, August 1–2. Teams of 2 to 4. 24 hours. ₹10,00,000 prize pool. 🧵 👇️

🚀 Build with the fastest database on the planet. Introducing Click-a-thon 2026 - ClickHouse's first in-person developer hackathon in India. 24 hours · ~120 developers · ~30 teams 📅 1–2 August 2026 · Bengaluru Pick your track: ➡️ Real-Time Analytics ➡️ Observability ➡️ Data Warehousing 🧵👇

and officially launching ClickHouse in Japan 🇯🇵 Why in person? Because the questions you get from a data engineer face-to-face aren't the ones you get on a Zoom call. And APJ is one of the fastest-growing regions for ClickHouse 🧵 👇️

and that feedback loop only works when the creator of the database is in the room. Huge thanks to every customer, partner, and community member who showed up. Full recap on the blog 👇 clickhou.se/4fLM9e6 #ClickHouse #RealTimeAnalytics #APJ #DataEngineering

clickhousectl v0.2.0 is out, bringing support for Postgres and ClickPipes. Your agents can now scaffold a full transactional + analytical stack locally, iterate against it, and push to Cloud when it's ready for prod. clickhou.se/4wLzu16

clickhouse.comclickhousectl v0.2.0: Postgres, ClickPipes and moreWe're releasing clickhousectl v0.2.0. This release adds Postgres, ClickPipes, SQL over HTTP, a few agent-friendly output tweaks, and a standalone Rust client library for the ClickHouse Cloud API.

Introducing clickhousectl: the official CLI for ClickHouse. Now in beta. You can use the CLI for local development and operating ClickHouse Cloud: manage versions, run local servers, and control your cloud services from the same interface. clickhou.se/41qoA2h

LLMs are smart. Sometimes, too smart. They can reach for advanced features before you've even run a single query. We wrote up the most common mistakes we see when AI generates ClickHouse schemas, drawn from real patterns across dozens of customer engagements:

pg_clickhouse is the fastest PostgreSQL extension on ClickBench. We built pg_clickhouse to let you query ClickHouse directly from Postgres. Rather than shoehorn analytics into Postgres, pg_clickhouse pushes down full query execution to ClickHouse. clickhou.se/4qM2v8u

clickhouse.compg_clickhouse is the fastest Postgres extension on ClickBenchThe pg_clickhouse extension minimizes the effort required to run typical analytics queries in Postgres by delegating execution to ClickHouse.

Postgres + ClickHouse is becoming the default architecture for applications that need both transactional and analytical workloads. With Postgres managed by ClickHouse, the two run side by side from day one. But migrating existing analytical workloads off Postgres isn't trivial. clickhou.se/4alI7pT

clickhouse.comAI-powered migrations from Postgres to ClickHouseAI can drastically accelerate migrating analytical workloads from Postgres to ClickHouse. To set your agents up for success, give them the right environment.

We're open sourcing pg_stat_ch, a PostgreSQL extension that turns every query execution into a structured event and streams it to ClickHouse. Kaushik Iska walks through how it works under the hood: clickhou.se/4rQ8VEG 🐘 It's Postgres Week at ClickHouse 🐘 Today through Feb 20th
