/**
 * This is the base implementation for a pass-through output adapter of a transactional key value store.&nbsp;
 * This implementation provides the "exactly once" guarantee.&nbsp;
 * A concrete operator should be created from this skeleton implementation.
 * <p>
 * "Pass-through" means it does not wait for end window to write to the store. It will begin transaction at begin window and write to the store as the tuples
 * come and commit the transaction at end window.
