A BufferedStore is a store that initially writes a buffer and eventually transports data to a destination. The fact that the store is Buffered is an implementation detail and interaction with the store should be transparent to the user.

Reading from a BufferedStore

Each read can be thought of as a query of the form do you have any X?

describe 1 is asking: do you have any data where record is 1?
fetch "count", 1 is asking: do you have any data where key is count and record is 1?
verify "count", 1,1 is aksing: do you have any data where key is count, value is 1 and record is 1
etc

Each component can answer that question in 1 of 3 ways:

Yes
No, because it was removed
No, because it was never added

Here is the matrix for how component responses should form an overall BufferedStore response:

Destination Response	Buffer Response	Overall Response
Yes	Yes	Yes
Yes	No, because it was removed
Yes	No, because it was never added
No, removed	Yes
No, removed	No, because it was removed
No, removed	No, because it was never added
No, never had	Yes
No, never had	No, because it was removed
No, never had	No, because it was never added
