The Daily Diff hits 104 editions; featured study shows cloud storage, not Postgres, is the scaling bottleneck

Arpit Bhayani's curated engineering newspaper The Daily Diff has reached 104 daily editions, each with 20 selected stories, blogs, and papers.
The featured piece: a 3.3-billion-row benchmark by Sai Srirampur shows gp3 EBS latency, not the database engine, quietly bottlenecks ingestion, autovacuum, and replication at scale. Write amplification and I/O contention cause table bloat and read-latency spikes; checkpoint bursts on network storage stall writes. Moving to local NVMe cuts WAL flush latency to microseconds, paired with async replicas and object-storage backups for node failure.
