Six months ago, we acquired Langfuse - the open-source LLM observability platform trusted by 19 of the Fortune 50. Here's the thinking behind it. clickhou.se/4eIfQuF

ClickHouse achieves the @awscloud Cloud Operations Competency. clickhou.se/4g2ESXF From infrastructure monitoring to security analytics to LLM observability, teams use ClickHouse to query full-fidelity logs, metrics, and traces in real time.

Back in March we took stock of geospatial in ClickHouse. clickhou.se/4ok6NEB An H3-indexed radius query over 10M NYC taxi rows ran in 0.006s, about 12x faster than a bounding box. There are six geometry types and WKT/WKB import from PostGIS and GeoParquet too.

We open-sourced Silk, a C++ fiber runtime for high-concurrency I/O. clickhou.se/4gGsBs0 The architectural bet: stackful fibers let any function yield without co_await climbing the call chain. For I/O workloads, the per-fiber stack cost is worth it.

ClickHouse is now a native connection in @NotionHQ Custom Agents. Connect ClickHouse Cloud with OAuth and ask about your data in plain language. The agent reads your schema, runs a read-only query, and answers in the doc. clickhouse.com/blog/notion-c…

At @ClickHouseDB , we've been working hard in delivering the most reliable Postgres and fastest experience, not just claiming it. WAL-RUS is another step in that direction. WAL-RUS delivers Postgres backup performance on par with existing tools while using 10× less memory. That means more memory is available for Postgres itself. It's part of our broader effort to build Postgres infrastructure that's both high-performance and resource-efficient. And it's fully open source. Contributing back to the community is a high priority for us, it's part of our DNA and where we come from.

Reliable backups are foundational to running Postgres in production. That's why we've open-sourced WAL-RUS, a Rust implementation of WAL-G designed to deliver more predictable memory usage while remaining compatible with existing Postgres backup and WAL archival workflows. Looking ahead, we plan to use WAL-RUS as part of our managed Postgres offering, helping us continuously optimize the reliability and performance of backups for our customers.
