服务器端 将得到的 ip 写入数据库： #! /usr/bin/env python # encoding: utf-8 # time : 2015-06-02 9:55:24 # use : rpc # 在 192.168.8.214 建立服务器端，用函数 redis_records_add 在 redis 中处理 ip import sys import redis reload(sys) sys.setdefaultencoding('utf8') from SimpleXMLRPCServer import SimpleXMLRPCServer def redis_con(host): r = redis.Redis(host='%s' % host, port='6379') return r def redis_records_add(key, value): try: conn = redis_con('192.168.8.214') # 判断 key 是否在 redis 中已经有值，如果有那么自增 1 ，如果没有 那么设置为 1 if conn.zscore(key, value): redis_score = int(conn.zscore(key, value))+1 conn.zadd(key, value, redis_score) return conn

I have a SQL Server table that I'm using as a queue, and it's being processed by a multi-threaded (and soon to be multi-server) application. I'd like a way for a process to claim the next row from the queue, flagging it as "in-process", without the possibility that multiple threads (or multiple servers) will claim the same row at the same time. Is there a way to update a flag in a row and retrieve that row at the same time? I want something like this psuedocode, but ideally, without blocking the whole table: Block the table to prevent others from reading Grab the next ID in the queue Update

I want to build a windows service that will use a remote encoding service (like encoding.com, zencoder, etc.) to upload video files for encoding, download them after the encoding process is complete, and process them. In order to do that, I was thinking about having different queues, one for handling currently waiting files, one for files being uploaded, one for files waiting for encoding to complete and one more for downloading them. Each queue has a limitation, for example only 5 files can be uploaded for encoding at a certain time. The queues have to be visible and able to resurrect from a

I want to make persisted queue in core hornetQ client. The problem is when I stop the server the queue and the data will be destroyed. How to make a queue persisted? My code is: import java.util.Date; import org.hornetq.api.core.TransportConfiguration; import org.hornetq.api.core.client.ClientConsumer; import org.hornetq.api.core.client.ClientMessage; import org.hornetq.api.core.client.ClientProducer; import org.hornetq.api.core.client.ClientSession; import org.hornetq.api.core.client.ClientSessionFactory; import org.hornetq.api.core.client.HornetQClient; import org.hornetq.api.core.client

We are creating some flows in NiFi and there might be some cases where the queues are being build up but due to some reason the flow doesn't work as expected. At the end of the day, i would like to clear the queues and somehow would like to automate it. The question is how can we delete the queues from backend? Is there any way we can achieve that? In addition to the explicit "Drop Queue" function Bryan mentioned, a couple other features you may be interested are the "Back Pressure" and "FlowFile Expiration" settings on connections. These allow you to automatically control the the amount of

I am willing to send email to list of email address using queue . Without using queue my code is working fine but with queue it's showing following error: Exception in Queue.php line 86: Serialization of 'Closure' is not allowed in /home/hizbul/Development/Projects/Laravel/fastskool/vendor/laravel/framework/src/Illuminate/Queue/Queue.php line 86 at serialize(object(SendMessageToStudent)) in Queue.php line 86 at Queue->createPayload(object(SendMessageToStudent), '') in DatabaseQueue.php line 81 at DatabaseQueue->push(object(SendMessageToStudent)) in Dispatcher.php line 184 at Dispatcher-

Suppose you have an iterable items containing items that should be put in a queue q . Of course you can do it like this: for i in items: q.put(i) But it feels unnecessary to write this in two lines - is that supposed to be pythonic? Is there no way to do something more readable - i.e. like this q.put(*items) Using the built-in map function : map(q.put, items) It will apply q.put to all your items in your list. Useful one-liner. For Python 3, you can use it as following : list(map(q.put, items)) Or also : from collections import deque deque(map(q.put, items)) But at this point, the for loop is

In standard a job I use this method to dispatch a Job: dispatch(new PurchaseJob($trxId, $method, $params)); Next I want to dispatch another Job to send email, but I want to split it to another separate queue. From what I read on Laravel 5.5 docs I could do this: SendEmailJob::dispatch($userEmail)->onQueue('send_email'); But it does not seems to work on Lumen 5.5. What could I do to make this work or is there any other method that are not stated in the docs? I just managed to find a way to dispatch the queue with the specified name in Lumen 5.5. public function toMail($notifiable) { $job = (new
