queue

问题 I have a problem concerning the fact that my queues are received by IronMQ but not fire off. Like i ask in this question: https://stackoverflow.com/questions/19200285/laravel4-ironmq-queue-are-not-executed But i see that inside my Iron dashboard, after i subscribe a new domain, then it is not added in any list. Probably IronMQ should display a list of Domains subscribed, isn't it? And this is probably the reason why my queues are not fire off. How can i fix the issue? Thanks! 回答1: I'm not

问题 My application creates resque jobs that must be processed sequentially per user, and they should be processed as fast as possible (1 second maximum delay). An example: job1 and job2 is created for user1 und job3 for user2. Resque can process job1 and job3 in parallel, but job1 and job2 should be processed sequentially. I have different thoughts for a solution: I could use different queues (e.g. queue_1 ... queue_10) and start a worker for each queue (e.g. rake resque:work QUEUE=queue_1 ).

问题 I have two threads. Thread A is pulling some elements from queue and thread B is adding some elements to the queue. I want thread A to go to sleep when the queue is empty. When thread B adds some element to the queue it should make sure that thread A is working. How can this be done in Java? 回答1: Use a BlockingQueue, which is: A Queue that additionally supports operations that wait for the queue to become non-empty when retrieving an element, and wait for space to become available in the

问题 I have been using jQuery's stop(true, true) method to clear running animations so the next one starts immediately. I noticed that the first parameter, clearQueue , clears the entire animation queue but the second parameter, jumpToEnd , only jumps to the end of the currently running animation and not the ones that were removed from the queue. Is there a way to have it clear and jump to the end of all queued animations? I've ended up chaining a few stop(false, true) calls instead, but this will

问题 I've built a simple queue in Go. It uses an internal slice to keep track of its elements. Elements are pushed onto the queue by appending to the slice. I'd like to implement .Pop() by removing the first element in elements . In many other languages, "popping" the first element of a list is a one-liner, which leads me to believe my implementation below is sloppy and verbose. Is there a better way? type Queue struct { elements []interface{} } func (queue *Queue) Push(element interface{}) {

问题 I have a blocking queue of objects. I want to write a thread that blocks till there is a object on the queue. Similar to the functionality provided by BlockingQueue.take(). However, since I do not know if I will be able to process the object successfully, I want to just peek() and not remove the object. I want to remove the object only if I am able to process it successfully. So, I would like a blocking peek() function. Currently, peek() just returns if the queue is empty as per the javadocs.

问题 I'm happily improving my web application that runs on a Apache Tomcat . An ActiveMQ JMS server is added to send and receive messages. I already can send and receive messages, but need help on the receiver side. How should my web app continuously listen to one queue to receive messages? New messages arrive and the server should act on them. Ex: add data to the DB or or send an message back. I can already send messages. This is code. ActiveMQConnectionFactory factory = new

问题 I'm trying to figure out what data type to use... Basically I want a FIFO queue that is thread-safe and will automatically throw out old enough items once it gets to a pre-specified limit. Well, actually, maybe more of a list, because I don't want the whole concept of pushing onto the queue and popping an item off the queue at which point it's no longer available. The use case is basically for a playlist where I would have up to 5 upcoming items, the currently playing item, and then about 20

问题 Let's say I want to I download 10,000 files. I can easily build a queue of those 10,000 files (happy to take advice if any of this can be done better), import request from 'request-promise-native'; import {from} from 'rxjs'; let reqs = []; for ( let i = 0; i < 10000; i++ ) { reqs.push( from(request(`http://bleh.com/${i}`)) ) }; Now I have an array of Rx.JS observable I've created from promises that represent my queue. Now for the behavior of what I want, I want to issue Three-concurrent

问题 I have a List<MyRichObject> with 50 instances in it. Each of the instances has 1 or 2 unique properties, but in a way they are all unique because there is only one at position in the list, etc. I would like to come up with a unique way to "hash" this List so it is unique from all of the other Lists. Is there a smart way to do that in .NET 4? The purpose is to create a kind of "monniker" for the Lists so they can be dumped into a queue and found later based on their unique value. Thanks. 回答1:
