Question

Following is my requirement:

On a periodical basis, a “request” needs to be enqueued into a queue
The different parameters of the “request”, the periodicity of execution, start date of execution, and the last run date are stored in a database.

There can be few thousands of such requests in the database.

Now, I want to write a scheduler which polls the database regularly, and when the current date is equal to the “last run date” + “periodicity”, the request should be enqueued.

Please suggest the alternatives availabe for schedulers

This scheduler should be capable of running on multiple hosts

Thanks,
Hima

Have you looked at Quartz Scheduler? It may well do all you need very simply. I haven’t used it myself, but I’ve heard good things about it.
