Databases

• Clustering organises the data on the disk:
  • An example of how this can improve performance: https://bclennox.com/the-postgres-cluster-command
• Long Table Names suck:
  • They make queries so much longer
  • Seriously.

UUID Foreign Keys

I liked the idea.

UUIDs suck:

• Visually they take up more space (e.g. result of queries)
• Harder to just remember the ID in your head when you need to
• Lose automatic (basic) ordering of rows
• Copying and pasting is much more difficult because double-click to copy does not include the quotes
