telegram.ext.Dispatcherwill create a single context for an entire update. This means that if you got 2 handlers in different groups and they both get called, they will get passed the same CallbackContext object (of course with proper attributes like .matches differing). This allows you to add custom attributes in a lower handler group callback, and then subsequently access those attributes in a higher handler group callback. Note that the attributes on CallbackContext might change in the future, so make sure to use a fairly unique name for the attributes.
Do not combine custom attributes and @run_async. Due to how @run_async works, it will almost certainly execute the callbacks for an update out of order, and the attributes that you think you added will not be present.
