The Floe team came from on-premise databases: We wrote our own userspace, collaborative, task-based kernel. We made a database without a buffer pool and created a subsystem to issue I/O in under 1000 cycles/request, outperforming io_uring. Our execution engine maximises joins per second and runs SQL queries with 5MB of query text to completion. Of course, we needed a query... Read More

Robotics produces high-volume time series alongside video and lidar, with different sampling rates, large payloads, and expensive GPU-based feature computation. These workloads shape the storage and featurization systems we are building at Eventual for pretraining-scale video/sensor data curation. We’ll show how standard open-source building blocks—Apache Iceberg, Parquet, object storage, and MP4—combine with careful database engineering to support these workloads at... Read More

In this presentation, we will discuss the history, architecture, testing, and challenges of the Turso database management system. Turso is an SQLite-compatible, open-contribution embedded database built in Rust. It has 300+ committers and 24K GitHub stars. Its feature set includes an async architecture for backends like io_uring and IOCP, and a multi-writer mode with a Hekaton-style implementation and a logical... Read More
