### AI overview

The article explains how large, wide, or oversized Postgres tables can create performance and reliability problems. It describes a cascade-delete incident that caused timeouts, excessive WAL generation, replica lag, primary overload, and an outage. It presents partitioning, vertical scaling, and sharding as possible approaches, emphasizing sharding with Neki as a solution for large Postgres tables.

### Source excerpt

Postgres presents pretty predictable performance problems when dealing with large tables. Sharding solves this.

### AI overview

PlanetScale describes how Neki, its sharded Postgres system, performs consistent encrypted backups at petabyte scale. The approach combines filesystem backups, archived WAL replay, object storage such as Amazon S3, and massive parallelism to back up databases without affecting production queries.
