Ably LiveSync is now available for public testing and aims to simplify real-time data synchronization. It's designed to work with any tech stack and protect applications from inconsistencies caused by dual-writes and scaling problems due to thundering herds. The product has three key components: a Database Connector, Ably Pub/Sub Channels, and a Models SDK. In its alpha release, LiveSync supports PostgreSQL with plans for other databases in the future. It addresses real-time data synchronization challenges by eliminating polling, providing seamless database to frontend sync, enabling transactional publishing of changes, offering state management support, being database agnostic, and ensuring a highly reliable and scalable infrastructure.
