Support for Redis

[chrba]

Hi,
Currently, only in-memory storage is supported. Are there any plans to support Redis in the near future? If not, I'd be happy to help! :-)

Do you have any guidelines for the implementation?

Here are my initial ideas:

• implement a Redis version for the PolicyStore, SchemaStore and DataStore Traits.

• Use an async connection pool, e.g., bb8

• Load/save policies, schema and entities directly from/to Redis.

• Since the Cedar engine requires the entire PolicySet for each authorization, keep the PolicySet in memory and synchronize it via Redis subscription on changes.

Looking forward to your Feedback.
Christian
