Talk 1: Scaling Writes on MySQL
Speaker: Graham Campbell

As your application scales, database performance can quickly become a bottleneck. While read replicas can help offload read traffic, they don’t address issues like excessive connections or high write volumes.

That’s where connection pooling and sharding come in. Sharding distributes data across multiple databases, reducing both the write load and the data volume per node. Connection pooling, meanwhile, optimises resource usage and brings some unexpected benefits along the way.

In this session, you’ll learn how to scale your database infrastructure beyond read replicas to handle heavy write loads efficiently. I’ll walk through how we implemented these techniques at Voxie, a SaaS platform for SMS marketing, enabling the system to onboard large enterprise customers who send more messages in two hours than all our other customers combined do in a week.

Food and drink

Food will be in the form of pizza - please let us know if you have any specific dietary requirements prior to the day and we will endeavour to meet your needs. We’ll also be providing a range of drinks.

Code of conduct

Like a large number of other communities, we have an anti harassment policy and code of conduct (https://www.meetup.com/York-Amazon-Web-Services-User-Group/pages/32649582/Code_of_Conduct/), in order to support the inclusive nature of our events. It is necessary for all attendees, speakers, sponsors and volunteers at any AWS Leeds to agree with the code of conduct.

Helping with diversity and inclusivity

The organising team for AWS York are keen to promote diversity and inclusivity, in terms of speakers, how events are run, and the composition of the organising team. If you would like to contribute to this aim, particularly if you think you have experiences that you might not consider to be typical for the majority of the tech community, we would be really excited to talk with you at the event.
