S3. System Design Cơ Bản – Phần 16: Message Broker. With the added benefit of data integrity, this allows the participants to rejoin the classroom experiences seamlessly. A message broker (also known as an integration broker or interface engine) is an intermediary computer program module that translates a message from the formal messaging protocol of the sender to the formal messaging … Pub/sub’s loose coupling makes it a powerful solution for many common engineering challenges. The cache evicts the least recently used (LRU) keys regardless of TTL set. Depending on your application, you may need to distribute them across multiple systems, in order to, for example: With pub/sub, you can seed caches asynchronously.

SignalR, a new technology from Microsoft that makes long polling practical and scalable, is the solution you’ve been waiting for to address the implementation headaches of pub/sub systems. Instead, the programmer “publishes” messages (events), without any knowledge of any subscribers there may be. As such, rather than waiting for a nearby client to make a related request, the data is already in the cache. Pub/sub messaging can be used to enable event-driven architectures, or to decouple applications in order to increase performance, reliability and scalability.
