Percona Live Featured Session with Bogdan Munteanu: Edgestore Multi-Tenancy and Isolation

Percona Live Featured SessionWelcome to another post in the series of Percona Live featured talk blogs! In these blogs, we’ll highlight some of the session speakers that will be at this year’s Percona Live conference. We’ll also discuss how these sessions can help you improve your database environment. Make sure to read to the end to get a special Percona Live 2017 registration bonus!

In this Percona Live featured session, we’ll meet Bogdan Munteanu, Software Engineer at Dropbox. His session is Edgestore Multi-tenancy & Isolation. Edgestore is Dropbox’s distributed metadata store, used by hundreds of products, services and features (both internal and external). Dropbox shares a single Edgestore deployment for all workloads, which has many benefits. At the same time it also poses challenges around multi-tenancy and isolation.

I had a chance to speak with Bogdan about Edgestore:

Percona: How did you get into database technology? What do you love about it?

Bogdan: I am very passionate about large-scale distributed systems, as well as storage in general. After joining Dropbox and learning about the scale, growth and technical challenges of Dropbox’s metadata store, I decided to jump in.

One thing I love about database and database services is that for every company and deployment, they are critical, highly impactful systems. You’re always in the thick of the action! 🙂

Percona: Your talk is called Edgestore Multi-tenancy & Isolation. What does Edgestore do in Dropbox’s environment?

Bogdan: Edgestore is the metadata store that powers most of Dropbox’s products and features. Built on top of thousands of MySQL shards, it currently serves over six million RPS and stores three-trillion-plus objects.

Percona: What are the challenges that you faced at Dropbox around multi-tenancy and isolation?

Bogdan: As I mentioned earlier, most Dropbox’s products and features use Edgestore. In order to achieve isolation, many companies end up allocating dedicated database clusters for each product, or enforce hard limits on how much RPS each product can send.

We took a different approach: Edgestore is a single cluster serving all traffic and workloads. As you can probably guess, sometimes different products generate loads that negatively impact others. The challenge is to isolate the different types of workloads and traffic so as to prevent this from happening.

Due to our growth, new use cases come up all the time. It’s critical to have a mechanism that quickly detects who is causing a performance-impacting load, and then throttles back that specific source.

Percona: What do you want attendees to take away from your session? Why should they attend?

Bogdan: I think it would be interesting for folks to learn about the Edgestore architecture and workloads, some of our internals and the mechanisms we use to scale a one-size-fits-all metadata store while maintaining 99.99% availability.

Percona: What are you most looking forward to at Percona Live 2017?

Bogdan: I am really excited about several of the scheduled talks and workshops. There is a really good line up this year. It is also a great opportunity to meet other folks with similar interests in database services.
