Supervisor-level replicator auth plugin callbacks#6070
Merged
Conversation
As discussed in the comments of the new IAM plugin in [1], it would be nice to
have a per-plugin supervisor-level context for each plugin. So, for example,
they can create some kind of a ETS cache table for their tokens. This is what
we implement here. The API is simple:
* `sup_initialize() -> Ctx`
* `sup_cleanup(Ctx) -> ok`
The APIs are optional to implement. The name pattern mirror the regular plugin
API names: `initialize(...) -> {ok, ..., Ctx}` and `cleanup(Ctx) -> ok`
