Neon's recent enhancements to its storage performance have focused on reducing latency, improving throughput, and optimizing resource usage. By implementing smarter sharding, the company has achieved a significant reduction in WAL (Write-Ahead Log) decoding work, resulting in a 2x increase in ingest throughput for large tenants. Additionally, compressing WAL transmission has decreased network bandwidth usage by 70%, while faster disk writes on Safekeepers have led to a 230% increase in WAL write throughput. Other improvements include reduced latency for sequential and index scans through page prefetching, which sped up schema finalization by 300%, and more responsive L0 compaction to lower read amplification and latency. The introduction of parallel, pipelined S3 uploads has doubled upload throughput, cutting ingestion benchmarks by 30 minutes. Finally, an improved shard split policy offers an 18% speedup in ingestion for medium-sized tenants and better load balancing for larger ones, laying the groundwork for continued performance enhancements in Neon's storage system.
