AI / Apache Burr Interview questions

What are app_id and partition_key used for in Burr?

Burr applications are keyed on two identifiers used by the persistence and tracking layers:

IdentifierPurpose
app_idUniquely identifies a single application run. A UUID is generated automatically if you don’t supply one.
partition_keyGroups related applications together, e.g. a user’s ID or email in a chatbot. Can be left None if not needed.

Both are set together via with_identifiers(app_id=..., partition_key=...) on the ApplicationBuilder, and can be read inside a running action by requesting the ApplicationContext via the special __context parameter.

Which Burr identifier would you use to group all of one user’s chatbot sessions together?
If you don’t supply an app_id when building a Burr application, Burr will:
