I have two servers – one Django, the other likely to be written in Python – and one is putting ‘tasks’ into a database and another is processing these tasks.
They share a database, but I want the processor to react quickly to new tasks rather than polling periodically.
Are there any straightforward ways for two Python servers to talk to one another, or does the task processor have to have web-hooks or something?
It feels there ought to be a blessed way to do this…
Look toward message brokers like ActiveMQ, RabbitMQ, ZeroMQ. They are designed to solve problems similar to what you’ve described.
I’m working on real-time MMORPG with server part written in Python and our daemons currently queue tasks to each other using ActiveMQ with STOMP protocol.
On low level message brokers keep socket connections to consumers, so it is more efficient than periodical polling.
