   > Sorry, I wasn't clear. I was suggesting that if we are going to cache Ids, 
that we may want to have them expire from the cache after some period of time. 
   
   The reason behind the caching is that it is expected that some ids are low 
cardinality and used very frequently.  With this in mind, wondering if we 
should have size limited and time limited caches.  The point of the caches is 
that we expect it to be small, size limiting it would guard against exceptions 
to that expectation.  Time limiting clears out junk that is not being used any 
more (like a table id for a table that was deleted).
