Uneven rolling partition

We have a table with ~10M rows.

Currently, new rows are added by users' activities, while 'old' ones are archived (and deleted), based on age and status.

90% of queries are for the most recent rows (those inserted in the last hour, 10-30K rows), 9% are for rows aged up to 5 days (~1M rows) and the rest is for 'old' rows.

Ideally, we would like to have 3 partitions ('hot', 'warm' and 'cold') and have rows moving between them automatically as they aged. Any suggestion on how to setup this ?
