    Default Database Lookup Cache Lifetime

    What's the lifetime for the cache when you select "Enable Cache?" on a Database Value Lookup? Assume I reuse a transformation several times within a job, is the cache refreshed each time the containing transformation is called?

    Cache is on a step basis.... it goes away when the transformation goes away... so if you use the same transformation multiples times you will have multiple caches.

    No date based expiration on the cache, when it's "full" the oldest entries will be removed (if my memory serves correct)
