For instance, a business critical job running in producton requires highest CPU and precedence over a print something job that a developer wants to print. Sometimes the processing order of the items in a queue needs to be based on priority of those items, rather than just the order they are created or added to the queue. Finally, we will see how to implement priority queue. The above example shows, that the most recently put into the queue is removed by get.ĥ. The above example uses a single thread to show how the elements are removed from the queue in the same order in which they are inserted.ģ. # if not empty get the numbers from queueĢ. If you do not, you may want to read some of the references before continuing.ġ. Note : This discussion assumes you already understand the general nature of a queue. Locking is generally handled for the caller. between creator and consumer threads safely. Queues can be used to pass data or any wide range of information e.g. The queue module provides a first-in, first-out (FIFO), Last-in, First out (LIFO) data structure suitable for multi-threaded programming.
