You will explore the brand‑new #[AsGrid] and #[AsFilter] PHP attributes that slash boilerplate and improve developer experience, then see a DataTable Component built on Symfony UX LiveComponent deliver reactive grid updates with zero JavaScript. Whether you maintain a complex admin panel or craft custom back‑office tools, you will be ready to harness the full potential of the Sylius Grid.

Can Swans Fly? Scaling Sylius in the Cloud
Gracjan JĂłzefczyk
tech
+ show description - hide description
Gracjan will answer a question that every ambitious gaming studio eventually asks: Can Sylius handle thousands of orders per hour when millions of players hit “buy” at once? Drawing on a real project that sold millions of copies in just days, he will show how Sylius thrives in cloud‑native architectures focused on scale, speed, and survivability. You will see a production‑ready blueprint that runs Sylius on AWS, including ECS for container orchestration, Aurora for resilient data storage, S3 and CloudFront for massive download payloads, and SQS for rock‑solid messaging. Gracjan will explain how FrankenPHP brings modern PHP hosting performance, then walk through the CI/CD pipelines, autoscaling policies, load‑balancing tactics, and A/B testing setups that keep launch‑day traffic smooth. From license‑key fulfillment to digital distribution at AAA scale, this talk equips you to build an eCommerce backbone that soars as high as any green swan in the cloud.
