Neon deep dive: WAL+S3 storage architecture for the era of agents
matei_zaharia · x · 2026-08-25
Neon published a deep dive on its Lakebase storage architecture, proposing a design where the WAL (Write-Ahead Log) serves as the single source of truth with S3 as the backing store. The article argues that while traditional databases are data-centric, modern agent workloads require operations on history. This WAL-centric timeline model better serves new demands, resolving friction points like deployment, cloning, and recovery.
