Sequential UUID Generators on SSD

After I shared the sequential UUID benchmarks a couple of weeks ago, one of the points raised in feedback was the choice of the storage space. I’ve intentionally used a fairly weak storage system (RAID10 on three 7.2k SATA drives) because I wanted to demonstrate the benefits. But a couple of readers suggested using SSDs might significantly reduce […]

Databases vs. encryption

Let’s assume you have some sensitive data, that you need to protect by encryption.

Sequential UUID Generators

UUIDs are a popular identifier data type – they are unpredictable, and/or globally unique (or at least very unlikely to collide) and quite easy to generate. Traditional primary keys based on sequences won’t give you any of that, which makes them unsuitable for public identifiers, and UUIDs solve that pretty naturally. But there are disadvantages […]
