| * This is the base implementation for a pass-through output adapter of a transactional key value store. |
| * This implementation provides the "exactly once" guarantee. |

| * <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. |
