Running Plone entrants asynchronously

When using Plone 4, I successfully created a subscriber event for additional processing while saving a custom content type. I did this using the interface Products.Archetypes.interfaces.IObjectInitializedEvent.

configure.zcml

<subscriber 
        for="mycustom.product.interfaces.IRepositoryItem
             Products.Archetypes.interfaces.IObjectInitializedEvent"
        handler=".subscribers.notifyCreatedRepositoryItem"
   />

subscribers.py

def notifyCreatedRepositoryItem(repositoryitem, event):
    """
    This gets called on IObjectInitializedEvent - which occurs when a new object is created.
    """ 
    my custom processing goes here. Should be asynchronous

However, additional processing can sometimes take too much time, and I was wondering if there is a way to run it in the background, that is, asynchronously.

Is it possible to trigger subscriber events asynchronously, for example, when you save an object?

Not out of the box. You need to add asynch support for your environment.

plone.app.async; ZEO , , . , .

, :

from plone.app.async.interfaces import IAsyncService

async = getUtility(IAsyncService)
async.queueJob(an_async_task, someobject, arg1_value, arg2_value)

:

def an_async_task(someobject, arg1, arg2):
    # do something with someobject

someobject - ZODB. IAsyncService.queueJob , , . .
