Internals

BoltDB is a low level database, so its out of the scope the implementation of TTL's go-oauth2 relies on the TTL implementations to ensure the correct deletion of the tokens.

This means this package also contains a TTL implementation over boltdb to ensure TTL's are correctly deleted

The approach is to create a bucket that will be called tsc.BucketName + "-ttl" This bucket will contain all the entries that have a TTL and when they should be deleted.

The key of the entry is when it should be deleted and the value the key to be deleted. A monitor will be executed every minut to ensure all the keys are deleted.

Currently the system has a low precision 2 runs every minute is very low

But since this package is used mainly for side projects that is not a problem at all. In case you need more precision ensure to open a PR that allow configurable sweep durations
