Overview

A transaction is just a list of operations, each on a specific table and key.

The ACID guarantees are not provided by this class. Rather, this class is just common representation of a (very simple) kind of transaction that can be used by Calvin and other transaction engines built on top of the system model.

Transactions submitted to Calvin are not as general as this class indicates. They should be split up into transactions each of which consists of reads followed by writes, and the row IDs of the writes should be independent of the read results. This is necessary for the Scheduler and the Readcaster protocols. (See the discussion of OLLP in the Calvin papers.)

Like the operations they are composed of, transactions are stateless and do not reference any particular store. Hence they can be re-used in different replicas.
