The SingleStore Helios cloud service has been developing its new Shared Tier for cost efficiency and fast deployment. The goal was to keep hundreds of users in the same underlying cluster while supporting existing APIs, improving free trials and developer experience, and increasing exposure to those who find the normal tier too expensive. To achieve this, a custom shared MySQL proxy was built on top of SingleStore's architecture, which detaches idle databases for cost efficiency and uses a proxy to automatically attach them. The proxy handles packet parsing, resource creation, and routing information, simulating interactions with existing database features. Despite some challenges, such as identifying a bug related to the MySQL protocol, the new tier is now available in preview, and design partners are encouraged to provide feedback.
