Real-Time Communication with Harper
Blog post from Harper
Harper is a distributed database that excels in real-time data distribution, traditionally using its publish/subscribe mechanism for internal replication across nodes. Recognizing the potential for broader applications, Harper is extending these capabilities to users, allowing for real-time message delivery and data synchronization without complex integrations. This is achieved via custom functions and new interfaces, including a Resource API for CRUD operations and real-time subscriptions, supporting protocols like WebSockets and MQTT. These developments facilitate efficient real-time communication, offering a consistent path for addressing resources and aligning pub/sub topics directly with database tables and records. The upcoming Harper 4.2 release promises further enhancements with an extensible plugin architecture, supporting additional protocols like AMQP and Server Sent Events, ensuring optimal integration and performance for real-time applications.
