Engine | ||
====== | ||
|
||
The Spinach :class:`Engine` is what connects tasks, jobs, brokers and workers | ||
together. | ||
|
||
It is possible, but unusual, to have multiple Engines running in the same | ||
Python interpreter. | ||
|
||
.. autoclass:: spinach.engine.Engine | ||
:members: | ||
|
||
Namespace | ||
--------- | ||
|
||
When multiple Spinach Engines use the same Redis server, for example when | ||
production and staging share the same database, different namespaces are used | ||
to make sure they do not step on each other's feet. | ||
|
||
The production application would contain:: | ||
|
||
spin = Engine(RedisBroker(), namespace='prod') | ||
|
||
While the staging application would contain:: | ||
|
||
spin = Engine(RedisBroker(), namespace='stg') | ||
|
||
.. note:: Using different Redis database numbers (0, 1, 2...) for different | ||
environments is not enough as Redis pubsubs are shared among | ||
databases. Namespaces solve this problem. |
