How lakebase architecture delivers 5x faster Postgres writes

Lakebase achieves 5x faster Postgres writes by eliminating the full page write bottleneck through compute-storage separation.

• •Traditional Postgres creates expensive full page images in write-ahead logs to prevent page corruption, causing up to 15x WAL volume overhead.
• •Lakebase's stateless compute eliminates the torn page failure by streaming WAL to Paxos-based storage instead of local disk.
• •Image generation pushdown moves page image creation from compute to distributed storage, reducing WAL traffic 94% while maintaining read performance through delta chain optimization.
• •Production benchmarks show 4.5x throughput gains on 32-vCPU instances with WAL generation reduced from 30 MB/s to 1 MB/s.
• •Read latencies improved 30-50% with regional WAL ingestion decreasing 4x and storage latencies improving 3x after fleet-wide deployment.
