MySQL stories - lessons worth stealing from BigBasket and Percona

BigBasket, one of India’s largest online grocery platforms, runs at high QPS with Terra-fic data sizes across hundreds of AWS instances. Keeping that running smoothly is no small feat, and this is the story of how BigBasket and Percona did it together. From hard-won MySQL 8.4 upgrades and production stability wins, to slashing storage costs and saving over $200,000 annually - this talk covers the real difficulties, the fixes that actually worked, best practices and the lessons you can apply to your own systems.

We will cover lessons you can steal for your own systems:

• Day-to-day operational challenges at scale
• Database stability & performance best practices
• 8.4 upgrade story - pre and post operations, what actually works
• Blue/Green deployment gotchas
• Large dataset cost optimisation
