Redis Spring Session - Indexes have a TTL of No Limit

[dreamstar-enterprises]

The issue I am encountering relates to the fact that while Spring Session / Security is saving my session data to Redis and applying a TTL (Time-To-Live) to the main session keys, the associated indexed keys (such as attributes indexed for lookups) are not automatically being set with a TTL. This means that these indexed keys can persist indefinitely unless manually deleted (e.g., through an explicit logout), leading to a potential memory leak.

Is there a way, and if not, can I request the ability to attach time limits to indexed components of sessions (e.g. in Redis). The normal session keys get cleaned up by Redis as they have a TTL, but as you can see below, when a session naturally expires, the other bits remain in Redis.

Is it right behaviour for when sessions expire and get removed for the Indexed keys to remain their indefinitely?

These should be removed by Redis based on a TTL assigned to them, just like with the hashed session key - or some cron function should be provided,
