Apache Kafka is a distributed event store and stream-processing platform. It is an open-source system developed by the Apache Software Foundation written in Java and Scala.The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds.
Hume—functional, concurrent, for bounded space and time environments where automata processes are described by synchronous channels patterns and message passing; Io—actor-based concurrency; Janus—features distinct askers and tellers to logical variables, bag channels; is purely declarative; Java—thread class or Runnable interface
Computer-supported collaborative learning (CSCL) is a pedagogical approach wherein learning takes place via social interaction using a computer or through the Internet. This kind of learning is characterized by the sharing and construction of knowledge among participants using technology as their primary means of communication or as a common resource. [1]
Asynchronous learning is a general term used to describe forms of education, instruction, and learning that do not occur in the same place or at the same time. It uses resources that facilitate information sharing outside the constraints of time and place among a network of people. [ 1 ]
Synchronous communication in distance education began long before the advent of the use of computers in synchronous learning. After the very early days of distance education, when students and instructors communicated asynchronously via the post office, synchronous forms of communication in distance education emerged with broadcast radio and television.

The dependency cannot be substituted, or its "signature" changed, without requiring a change to the dependent class. Loose coupling occurs when the dependent class contains a pointer only to an interface, which can then be implemented by one or many concrete classes. This is known as dependency inversion. The dependent class's dependency is to ...
Synchronous transactions in EDA can be achieved through using request-response paradigm and it can be implemented in two ways: [1] Creating two separate queues: one for requests and the other for replies. The event producer must wait until it receives the response. Creating one dedicated ephemeral queue for each request.
Distributed learning may be dependent on time if it includes synchronous sessions, and further time dependent if the course is paced. The oldest and most commonly used of these terms, distance education, can be used to describe distributed learning as defined above. "Distributed education" lacks a correspondence school tone and history and thus ...
