The maximum number of subscriptions per WebSocket connection is _____.

The maximum number of subscriptions per WebSocket connection is indeed 1,000. This limit is important for maintaining optimal performance and resource management within the system. Each subscription within the WebSocket connection represents a channel through which data is sent and received, and having a maximum of 1,000 subscriptions ensures that the system can handle a significant amount of real-time data while preventing potential overload.

In real-world applications, this limit allows developers to build scalable applications that can manage multiple clients and their corresponding data streams effectively. It strikes a balance between flexibility for various application use cases and the performance constraints inherent in handling live data streams.

Other options present lower limits, which would not adequately support applications requiring a broader range of subscriptions for various features or greater complexity in data handling. The choice of 1,000 subscriptions reflects a design decision that emphasizes both the capacity and efficiency needed in modern web applications.
