   @alamb Thanks for the initial review and comments! I think there's one key 
decision that needs to be made before moving forward in earnest here, which is 
what action we should take with the cache for `INSERT` statements. 
   
   > One very key omission here that needs to be discussed is how INSERT 
statements are handled. On the surface it seems like there are two options:
   >
   >    1. Invalidate the cache key(s) associated with the table that 
corresponds to the INSERT statement
   >    2. Intercept the object(s) that correspond to an INSERT statement and 
add them to the cache
   >
   > The first option here seems much easier, but the 2nd option seems more 
ideal since a user is likely to issue a query against newly inserted data. 
   
   Do you have any thoughts or preferences on this?
