TimesTen allows rows to be 'AGED' - either in a regular table, or within a cache group.
The aging policy you define can be usage based (LRU) or Time Based. This note will discuss Time Based aging.
Time-based aging removes data from tables / caches based on the user specified 'lifetime' and frequency (cycle) of the aging process. You can define both usage-based aging and time-based aging in the same data store, but you can define only one type of aging on a specific table.
This note seeks to answer what formula is used to determine if a row should be 'AGED' when time based aging (rather than LRU based aging) is in use.
