Architectural Comparison

Kolmos vs MySQL:
InnoDB Page Bloat vs R2 Columnar Efficiency.

MySQL powers millions of web applications worldwide. Kolmos gives you the identical MySQL wire protocol on Port 3306 while freeing you from InnoDB fragmentation and expensive cloud EBS volumes.

When to Stick with Standard MySQL

  • Applications heavily dependent on legacy MySQL stored procedures or triggers.
  • Small databases where cloud infrastructure spend is below $20/month.

When to Choose Kolmos

  • High-volume analytical queries that cause table locks or CPU stalls on standard MySQL.
  • Cutting storage and IOPS expenses by up to 85% by moving to Cloudflare R2 storage.
  • Zero code refactoring: connect using your existing Laravel, Node.js, or PHP credentials.
