Open House observability announcements: MCP server, AI Notebooks, and ClickStack Cloud
At Open House, ClickHouse announced three observability updates: ClickStack Cloud entered private preview, AI Notebooks entered beta for Managed ClickStack, and a ClickStack MCP server was introduced in open-source ClickStack. ClickStack Cloud is a fully managed, serverless platform that accepts OpenTelemetry data through a managed endpoint, while Managed ClickStack is generally available for teams controlling collectors, ingestion, compute sizing, schema design, and tuning. AI Notebooks provide a persistent, shareable investigation workspace in which prompts, queries, charts, reasoning steps, findings, branches, intermediate results, and generated queries remain visible and editable. The MCP server exposes the investigative tools used by Notebooks to external agents, routing requests through optimized searches, aggregations, and visualizations rather than relying entirely on ad hoc SQL generation; it can also persist findings in dashboards. Together, the announcements present a choice between managed convenience, operational control, and programmable observability workflows.
Thank you for building with us
At its 2026 user conference in San Francisco, ClickHouse reports surpassing 4,000 customers and $250 million in annual run-rate revenue, while marking nearly ten years since Alexey Milovidov open-sourced the database. The company attributes its growth to a community of contributors and describes use across AI products, financial services, observability, analytics, and infrastructure. New offerings include ClickHouse Agents, a fully managed agentic analytics service powered by Anthropic’s Claude; CostBench, an open benchmark using each warehouse’s real billing model; and House Mates, a partner program launching with more than 50 partners across six continents. Additional updates include Managed Postgres in public beta, Managed ClickStack and Langfuse for AI-era observability, generally available full-text search, and automatic JOIN optimization, with cost-performance identified as the central constraint for high-concurrency, low-latency workloads.
ClickHouse tops $250M ARR and 4,000 customers, launches Claude-powered agents at Open House 2026
At Open House 2026, ClickHouse announced that its serverless cloud offering exceeded $250 million in annual run-rate revenue and reached 4,000 customers, with ARR more than tripling year-over-year and more than 1,000 net new customers added since January.

Introducing Always-On pricing: automatic savings for Databricks Lakebase
Databricks introduces Always-On pricing for Lakebase, offering a lower rate for baseline compute while retaining elastic autoscaling. On any Lakebase Postgres Autoscaling project, operators turn off scale-to-zero and set an autoscaling range; the minimum capacity becomes the baseline, which receives the lower rate after 24 hours of continuous use. Capacity above the minimum continues to autoscale up to the configured maximum and is billed at standard Autoscaling rates, while users can re-enable scale-to-zero later. The pricing targets established workloads with a consistent activity floor; intermittent or new workloads can retain scale-to-zero to avoid paying for idle hours and uncertain baseline estimates. The announcement says the baseline price is 25% lower, and an additional 50% promotional discount runs through January 31, 2027.
Announcing Lakebase Change Data Feed (CDF)
Lakebase Change Data Feed (CDF) is available in Public Preview to reduce the manual effort of moving data from operational databases into downstream systems. The feed is enabled once for all tables in a project, stored and governed in Unity Catalog Managed Tables, and readable by engines, models, and agents without separate extraction pipelines. From one shared feed, teams can build streaming pipelines with SDP, create materialized views with DBSQL, or compute and store embeddings with Agent Bricks, while consumers remain isolated from the primary operational workload. The announcement positions Lakebase as the native Bronze layer in a medallion architecture, complementing Synced Tables and providing governance and lineage across the data lifecycle.
Role-Based Access Control for humans and agents
Modal announced Role-Based Access Control for Team and Enterprise users, enabling teams to grant agents and humans precise workspace access within Environments. Environments are workspace subdivisions with dedicated storage, apps, and limits, commonly set as dev-staging-production or per-developer. These now act as enforceable security boundaries through Restricted Environments, where workspace members are read-only by default and only explicitly assigned users or service users can deploy or manage resources. The RBAC system distinguishes human developers, AI agents, CI deployers, and external callers with recommended identities and environment access patterns, such as service users for agents and proxy auth tokens for external callers. Built on a new permissions architecture running for months, RBAC ties into Audit Logs and is the first of planned tools; future additions include spending limits and programmatic permissions.
Introducing House Mates: the ClickHouse partner community and program
ClickHouse introduces House Mates, a partner community and program bringing together more than 60 ISV, consulting, services, and channel partners to help customers build, scale, and procure ClickHouse solutions. The inaugural cohort includes over 25 ISVs developing validated, production-ready integrations—among them dbt Labs, Fivetran, Temporal, Grafana Labs, Confluent, and Sigma—and over 35 consulting, services, and reseller partners trained and certified through ClickHouse Academy. The program addresses an ecosystem with more than 200 integrations in the wild, demand for trusted regional expertise and preferred procurement channels, and the limits of managing partnerships through one-off arrangements. Its Ignite, Accelerate, and Prime tiers define progression from enablement and first projects or integrations to deeper go-to-market, incentives, co-innovation, and strategic collaboration at scale, while customers gain validated tools, regional experts, and preferred purchasing routes.
5 countries, 12 days, one ClickHouse: inside Alexey's APJ AI Tour
ClickHouse CTO and creator Alexey Milovidov completed a 12-day APJ tour spanning India, Singapore, Indonesia, South Korea, and Japan, with customer meetings, industry events, executive sessions, press interviews, and community meetups. The itinerary covered six cities and included three Confluent Data Streaming World Tour events, four ClickHouse meetups, and more than 10 enterprise customer meetings across varied industries and workloads. Discussions centered on real-time analytics, connected products, and analytics at industrial scale, while in-person conversations supplied feedback that the post says helps improve ClickHouse. The trip concluded with the ClickHouse Japan Launch Event on April 27, marking the company’s official entry into that market. The account presents physical presence as a way to extend ClickHouse’s open-building culture beyond GitHub and strengthen its feedback loop with APJ customers and communities.
Open House 2026 Day 1: Real-time data without lock-in and what teams can build next
ClickHouse’s Open House 2026 Day 1 announced updates spanning ClickHouse Cloud, Postgres, distributed query execution, observability, AI agents, and lakehouse interoperability. ClickHouse Postgres entered public beta with local NVMe storage, high availability, S3-backed point-in-time recovery, and a native CDC path into ClickHouse; early benchmarks reported more than 5x the transactions per second of AWS RDS. Multi-stage distributed queries repartition intermediate data between stages to scale joins and high-cardinality aggregations, reducing TPC-H SF100 runtime from 117.6 seconds on one node to 54.7 seconds on eight nodes. Additional launches included a Claude-powered ClickHouse Agents public beta, an AI-enhanced query builder, Monitoring v2, and Langfuse V4’s reported 200x query performance improvement, while the wrap-up framed the releases around real-time systems without lock-in.
Introducing ClickStack Cloud: Serverless observability powered by ClickHouse
ClickStack Cloud is entering private preview as a fully managed, serverless observability service built on ClickHouse for teams that want ClickHouse-powered logs, metrics, and traces without operating the underlying infrastructure. Users send OpenTelemetry data to a managed OTLP endpoint, while the service handles ingestion, durable buffering through an object-storage-backed event queue, scaling, storage, and query serving, then exposes telemetry in the ClickStack UI with integrated authentication and RBAC. The preview separates ingestion and query resources and is developing automatic tuning based on query patterns, including materialized fields, primary-key adjustments, materialized views, and indexes. Dedicated query compute for agentic and high-volume analytical workloads is planned after the preview, while pricing remains unfinished and the existing Managed ClickStack offering remains intended for teams requiring direct infrastructure and schema control.
Postgres managed by ClickHouse is now in beta
ClickHouse Cloud has launched a fully managed Postgres service in beta to combine transactional and analytical workloads within a single platform. Backed by local NVMe storage, the service provides up to ten times faster transactional performance alongside native change data capture into ClickHouse. Developers can query across both transactional and analytical layers using the pg_clickhouse extension without managing custom data pipelines. The platform also offers managed migration workflows via ClickPipes, database branching, point-in-time recovery, high availability with up to two standbys, and support for over ninety PostgreSQL extensions. More than fifty virtual machine configurations are available, ranging from single vCPU instances to clusters with ninety-six vCPUs and sixty terabytes of NVMe storage.
Introducing multi-stage distributed query execution in ClickHouse Cloud
ClickHouse Cloud introduced multi-stage distributed query execution to improve scaling for large joins and high-cardinality aggregations across multi-node clusters. Prior execution models relied on physical sharding or parallel replicas, which lacked the ability to freely repartition intermediate data between query stages. By splitting query plans into stages connected by exchange operators, worker nodes can shuffle, broadcast, scatter, or gather intermediate data during execution. In TPC-H benchmarks at scale factor 100 on eight nodes, total query time dropped from 117.6 seconds to 54.7 seconds, with scan-dominated queries showing near-linear 7.4x speedups. While currently in private preview with a rule-based planner, future work includes developing a cost-based optimizer to select optimal aggregation and join strategies automatically.
Your agent can't fix what it can't see
Coding agents frequently fail to resolve production bugs when restricted to source code alone, as they lack critical runtime context such as stack traces, breadcrumbs, and environment data. To bridge this gap, Sentry introduces Sentry MCP and the Sentry CLI to supply agents and developers with structured production telemetry. The Model Context Protocol integration supports clients like Claude Code, Cursor, and VS Code, while the CLI enables scripted workflows. When an alert triggers, an agent uses trace and commit metadata to diagnose root causes across service boundaries, generate regression tests, and open draft pull requests. Over six months, the Autofix pull request merge rate increased from 41% to 46%.
Accelerating LLM Inference with Prompt Caching for Open‑Source Models on Databricks
Repeatedly processing identical system or instruction prompts for LLM requests wastes compute, increases latency and costs, and limits throughput. Databricks extends its built-in prompt-caching capability from proprietary models to open-weights models used through Foundation Model APIs, including batch inference, pay-per-token, provisioned throughput, and higher-level services such as Agent Bricks, Genie, and AI Functions. Supported models include GPT-OSS 20B and 120B, Gemma 3 12B, fine-tuned Llama 3.1 8B via PEFT serving, and Llama 3.1 8B and 3.3 70B. By implicitly reusing KV caches for identical prompts, the system skips prefill on cache hits; caches are isolated, held only in volatile memory, and never persisted. In a production GPT-OSS batch-inference pipeline, per-replica input-token throughput rose 2.5x and P50 latency fell 3x despite a 30% cache hit ratio, with no customer configuration required.
Cursor named a Leader in the 2026 Gartner® Magic Quadrant™ for Enterprise AI Coding Agents
Gartner named Cursor a Leader in the 2026 Magic Quadrant™ for Enterprise AI Coding Agents, with Cursor positioned furthest on Completeness of Vision. Cursor reports that more than 70% of the Fortune 500 use its platform to deploy and manage coding agents across the software development lifecycle, while its stated direction centers on developers orchestrating large teams of agents. The roadmap combines expanded in-house model training, including Composer 2.5 and a planned future model built with SpaceXAI, with automation through Bugbot, security agents, scheduled Automations, and the Cursor SDK. It also calls for deeper enterprise controls, admin integrations, analytics dashboards, and broader availability of self-hosted cloud agents for regulated industries and regions.
