gearman

问题 From what I can see Gearman does not support scheduled jobs or delayed jobs. I was thinking that perhaps the scheduled job could be queued in at first and then added to the Gearman queue after the at time period has expired. at tasks are persistent as they are written as files to a directory in the spool directory of the server. So the only bottle neck would potentially be a simple script to add the task to the Gearman queue because at can't be distributed across servers. Passing it to

问题 I want to be able to query a gearman server to determine how many instances of a worker I have running (basically I want to make sure that RunTaskA is available and RunTaskB is available if there are no workers handling those tasks, I want to be able to send an alert out. Is there any way to do this? Also: Mad props if you know of a PHP way to query the gearman server. Edit : I know about the PHP gearman extension that is available natively, but I am not looking for a task submission

问题 Unfortunately the package hgearman does not provide any test or example and I can't work it out for myself how should be combined connectGearman and submitJob to put a job to the gearman job server. The result of connectGearman is: ghci> conn <- connectGearman (B.pack "x") ("localhost"::HostName) (4730::Port) ghci> :t conn conn :: Either GearmanError GearmanClient but submitJob uses private function submit which deals with StateT . So I can only guess the result of connectGearman should be

问题 I am making a thumbnail generator, and I am using Gearman to do the job in the background as soon as a photo is uploaded. I have a worker written in Node.js which basically does the thumbnail processing(using imagemagick for node) and inserting it into the database. The Client side is written in PHP, where it basically send the Photo_id and the base64 encoded string of the original image. The Node.js worker takes the input base64 encoded image, and processes it. Everything is working fine.

问题 Has anyone ever tried and succeeded to install gearman extension on MAMP?

问题 In a nutshell : I want to have an overall timeout for a call to runTasks() in a Gearman client. I feel like I can't be the first person to want this, but I can't find an example of how to put it together. Here's what I want to achieve: In a PHP script, use the Gearman client to start a series of jobs in parallel Each job will produce some search results, which the PHP script will need to process Some of the jobs may take some time to run, but I don't want to wait for the slowest. Instead,
