Overview
Explore the latest developments in FoundationDB's Redwood storage engine in this 21-minute conference talk by Steve Atherton from Apple. Gain insights into the B-Tree based engine designed for higher I/O throughput and reduced on-disk footprints. Learn about current features, performance characteristics for various workloads, and potential caveats. Discover the project's status, including completed and pending tasks, and understand the impact of prefix compression on performance. Delve into the original and updated pager designs, and examine I/O patterns for writes, large GetRange operations, and deferred range clears. Conclude with a look at planned future optimizations to enhance Redwood's capabilities.
