 From google paxosdb paper:
 Our implementation hinges around a powerful primitive which we call MultiOp. All other database
 operations except for iteration are implemented as a single call to MultiOp. A MultiOp is applied atomically
 and consists of three components:
 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
 for the absence or presence of a value, or compare with a given value. Two different tests in the guard
 may apply to the same or different entries in the database. All tests in the guard are applied and
 MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
 it executes f op (see item 3 below).
 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
 lookup operation, and applies to a single database entry. Two different operations in the list may apply
 to the same or different entries in the database. These operations are executed
 if guard evaluates to
 true.
 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.
