queue-table

I am implementing a small queue to handle which process gets to run first. I am using a table in a database to do this. Here is the structure of the table (I'm mocking it up in SQLite): "id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL , "identifier" VARCHAR NOT NULL , "priority_number" INTEGER DEFAULT 15, "timestamp" DATETIME DEFAULT CURRENT_TIMESTAMP, "description" VARCHAR I am trying to write SQL to give me the row of which process can run next. Here is some sample data: id identifier priority_number timestamp description 1 test1 15 2009-01-20 17:14:49 NULL 2 test2 15 2009-01-20 17:14:56 NULL

I need to implement a queue using table. The business requirement is to have a single queue which will be accessed by 5-10 boxes to get the next job/jobs. There will not be more than 5000 jobs per day. Also, a batch of jobs should be "dequeued" at one time. Just wondering what are the problem areas and issues I might run into as I havent done it before. If anyone has faced this/done this before, can you please point me to a design/sample implementation or issues that need to be taken care of. Thanks There are a lot of general purpose queuing or messaging services. Even if you want to implement
