Databricks has introduced a new lakebase architecture that significantly enhances PostgreSQL write performance, achieving up to a 5x improvement for write-heavy workloads. This architecture separates compute and storage, allowing critical crash-recovery tasks to be offloaded to distributed storage. By eliminating full page writes and implementing image generation pushdown to the storage layer, the system reduces WAL traffic by 94% and read tail latency by 2x, all while maintaining data durability.
