Describe the enhancement

Currently you can only set one purge_keep_days for everything, i would like separate options for entities with statistics (for there raw data not the statistics itself) and for those without. A minimum number of state changes to keep is an other solution, preferably both.

Use cases

In order to keep data for ententes without statistics for longer you are forced to keep raw data for everything for longer, this makes the database huge and also backups unmanageable big. Sins most entities without statistics changes less frequently, keeping a minimum number of changes (preferably in combination with separate purge_keep_days) lets you keep the data longer without making the database huge.

Anything else?

Increasing purge_keep_days and making an automation that runs recorder.purge_entities is almost a solution but currently not a practical one. The problem is that the sensor domain is huge and i want to purge all except a few. Currently i haw to list every entity i want to purge, using globs make it a little bit easier. Adding the ability to exclude entities/globs could make this a feasible solution.
