Environment Variables
|
|
======================
|
|
|
|
Eventlet's behavior can be controlled by a few environment variables.
|
|
These are only for the advanced user.
|
|
|
|
EVENTLET_HUB
|
|
|
|
Used to force Eventlet to use the specified hub instead of the
|
|
optimal one. See :ref:`understanding_hubs` for the list of
|
|
acceptable hubs and what they mean (note that picking a hub not on
|
|
the list will silently fail). Equivalent to calling
|
|
:meth:`eventlet.hubs.use_hub` at the beginning of the program.
|
|
|
|
EVENTLET_THREADPOOL_SIZE
|
|
|
|
The size of the threadpool in :mod:`~eventlet.tpool`. This is an
|
|
environment variable because tpool constructs its pool on first
|
|
use, so any control of the pool size needs to happen before then.
