Sequential UUIDs, like UUIDv7, offer a compelling alternative to UUIDv4. They maintain global uniqueness while providing better data locality, significantly reducing index fragmentation and improving write performance in Postgres. #UUIDv7 3/6

Sequential UUIDs, like UUIDv7, offer a compelling alternative to UUIDv4. They maintain global uniqueness while providing better data locality, significantly reducing index fragmentation and improving write performance in Postgres. #UUIDv7 3/6
UUIDv4 keys in Postgres often cause performance bottlenecks. Their random nature leads to severe index fragmentation, increasing disk I/O operations and slowing down queries. This is a significant concern for high-volume write workloads. #DatabasePerformance 2/6

UUIDv4 keys in Postgres often cause performance bottlenecks. Their random nature leads to severe index fragmentation, increasing disk I/O operations and slowing down queries. This is a significant concern for high-volume write workloads. #DatabasePerformance 2/6
Overview: Hacker News debated Postgres primary keys: UUIDs vs. integers. Key trade-offs explored include performance implications (index fragmentation), security concerns (information leakage), and complexities in distributed systems like sharding. A critical architectural decision. #Postgres 1/6
