Tim Callaghan - Fractal Tree Indexes: Theory and Practice

  • Jul 17, 2013 · 6:30 PM
  • Wayfair Offices - 4 Copley Place

Improvements in index theory and practice can greatly improve performance for modern applications with big data sets. My presentation will cover Fractal Tree Indexes and how they enable numerous advantages in MySQL (TokuDB) and MongoDB (TokuMX).

Tim spent the 90's leading all Oracle development at Investors Bank & Trust and the 00's crafting a distributed Oracle based SaaS application at CrunchTime! (  Tim is currently the Vice-President of Engineering at Tokutek (, helping to bring the power of Fractal Tree Indexes to MySQL and MongoDB. Along the way he has dabbled in other databases and too many programming languages to list.


We're also switching it up this month - Tokutek will be providing beer and wings instead of pizza!
