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.

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. Read more about why we built it and the engineering behind it: clickhouse.com/blog/walrus-p…

It wouldn't be a release call without an exploration of performance improvements. First, and a big highlight, ClickHouse Keeper is 2x faster!!!
