Dagster gave partitioned automation a performance boost and introduced a mobile UI, and pg_clickhouse and chdb tightened type and encoding handling. ### ClickHouse bets big on Microsoft The week's headline is ClickHouse's push into Microsoft's data ecosystem. A [native Fabric workload](https://clickhouse.com/blog/clickhouse-for-microsoft-fabric) brings sub-second analytics to OneLake data in public preview, backed by dedicated ClickHouse Cloud compute for agents, dashboards, and applications. Alongside it, ClickHouse can now [write Apache Iceberg tables directly to OneLake](https://clickhouse.com/blog/clickhouse-now-writes-to-microsoft-onelake), making the lake a first-class landing zone for analytical workloads. Both arrive under a broader [expanded Microsoft collaboration](https://clickhouse.com/blog/clickhouse-expands-collaboration-with-microsoft) that adds OneLake read and write capabilities and makes ClickHouse BYOC available in the Microsoft Marketplace. ### Cloud identity and the operational layers On the managed side, ClickHouse Cloud picked up [SCIM 2.0 provisioning](https://clickhouse.com/blog/introducing-scim-provisioning-in-clickhouse-cloud), so an identity provider can create, update, and deprovision organization members and sync group membership to ClickHouse roles automatically — a meaningful change for teams wiring enterprise SSO into their analytics stack. The blog also dug into the internals of its managed Postgres: a piece on [why direct I/O backs its backups](https://clickhouse.com/blog/direct-io-managed-postgres-backups) explains how stripe-sized reads keep backups fast without polluting the page cache and hurting query latency, and a [recursive query benchmark](https://clickhouse.com/blog/can-your-postgres-survive-a-bad-query) compares whether Postgres clusters survive a memory-exhausting query against Cloud SQL, PlanetScale, and Amazon RDS. ### Extensions, encoding, and agent memory The Postgres bridge saw real polish: the [latest pg_clickhouse and chdb releases](https://clickhouse.com/blog/pg_clickhouse-chdb) improve character encoding, interval handling, nested data, JSON, and type mappings between the two engines. ClickHouse also published a [memory-safety walkthrough for its Postgres extensions](https://clickhouse.com/blog/memory-safety-postgres-extensions-c-cpp), covering the challenges of mixing C and C++ — clean language boundaries and isolated helper processes — which pairs naturally with the extension work above. For the agent crowd, the [chDB Durable Layer](https://clickhouse.com/blog/chdb-durable-layer-for-agent-memory) keeps agent memory fast to query locally while making its analytical state recoverable across laptops, CI jobs, and short-lived sandboxes. And behind all of this, ClickHouse kept its release trains moving: a [steady stream of stable and LTS updates](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.9.10.4-stable) across the 26.3, 26.7, 26.8, and 26.9 lines, spanning [dozens of patches](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.7.21.2-stable) shipped throughout the week. ### Dagster goes mobile, Tinybird sets a kernel floor Dagster's week centered on scale and access: its [partitioned declarative automation got faster](https://github.com/dagster-io/dagster/releases/tag/1.13.25) for assets with long materialization histories, and the UI now has [a proper mobile layout](https://github.com/dagster-io/dagster/releases/tag/1.13.25) with navigation and mobile versions of Home, Jobs, Automation, and the Asset Catalog. Tinybird, meanwhile, flagged a [4KiB page-size requirement for arm64](https://www.tinybird.co/docs/changelog/2026-10-02-october-week-one) Tinybird Local images — most distributions are fine, but kernels with larger pages won't start ClickHouse, so arm64 users may need to switch flavors or fall back to amd64. ## Releases covered ### ClickHouse - [ClickHouse Workload for Microsoft Fabric: sub-second analytics on OneLake, now in public preview](https://clickhouse.com/blog/clickhouse-for-microsoft-fabric) - [ClickHouse now writes Apache Iceberg tables to Microsoft OneLake](https://clickhouse.com/blog/clickhouse-now-writes-to-microsoft-onelake) - [ClickHouse expands collaboration with Microsoft, bringing Fabric integration, deeper OneLake interoperability, and enterprise deployment flexibility](https://clickhouse.com/blog/clickhouse-expands-collaboration-with-microsoft) - [Introducing SCIM Provisioning in ClickHouse Cloud](https://clickhouse.com/blog/introducing-scim-provisioning-in-clickhouse-cloud) - [What is direct I/O, and why does ClickHouse Managed Postgres use it for backups?](https://clickhouse.com/blog/direct-io-managed-postgres-backups) - [Can your Postgres survive a bad query?](https://clickhouse.com/blog/can-your-postgres-survive-a-bad-query) - [pg_clickhouse & chdb updates: Encoding, nesting, and types](https://clickhouse.com/blog/pg_clickhouse-chdb) - [Memory safety for Postgres extensions in C/C++](https://clickhouse.com/blog/memory-safety-postgres-extensions-c-cpp) - [chDB Durable Layer for agent memory](https://clickhouse.com/blog/chdb-durable-layer-for-agent-memory) - [Release v26.9.10.4-stable](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.9.10.4-stable) - [Release v26.7.21.2-stable](https://github.com/ClickHouse/ClickHouse/releases/tag/v26.7.21.2-stable) ### Dagster - [1.13.25 (core) / 0.29.25 (libraries)](https://github.com/dagster-io/dagster/releases/tag/1.13.25) ### Tinybird - [Tinybird Local on arm64 requires a 4KiB page size kernel](https://www.tinybird.co/docs/changelog/2026-10-02-october-week-one)
