Message queue: it can handle multiple tasks that are lined up for processing
- What is a queue: a collection of entities that are maintained in a sequence and can be modified by the addition of entities at one end of the sequence and the removal from the other end. This characteristic is known as FIFO (First In, First Out), meaning that the first element that gets added to the queue is the first one to be removed.
- tasks can be lined up in a queue for sequential processing.
- The ability to use Redis as a queue opens up a wide range of possibilities for handling distributed jobs and messages, especially in applications that require high performance and reliability.
Implementing a basic queue in Redis:
- The primary data structure used for this purpose is the Redis List, which is a list of strings sorted by the order of insertion.
