Interface ITransactedKeyValueTable<TKey, TValue>

A key value table that operates in the scope of a transaction. For example, if the transaction has snapshot isolation, this acts on a snapshot of the table. Note that the implementation of this data structure is not required to be thread safe. Concurrent reads and/or writes may corrupt the invariants of the implementation.
