Percona Live Online

Venmo's Aurora database clusters are the centerpiece of its success, but it's not without its own operational challenges like upgrading from one major version to another. To unlock performance efficiency and operational costs, we had to rely on a number of Open Source tools to make a successful non-event upgrade possible.

- Percona Monitoring and Management to measure query performance.
- pt-upgrade to validate queries between versions.
- ProxySQL for a virtually no downtime switchover/rollback.
- In-house tools to bridge some gaps in testing.

During this talk, we will piece together these tools and the process we followed to not let Venmo users down.
