On the other hand, a good cache solution must guarantee consistency of data while allowing multiple transactions to read/write data concurrently.

Concurrency control is an activity that is important to avoid unexpected results; its primary goal is to ensure that all transactions will have the same effect as a serial one.

Traditionally, the problem of concurrency is solved providing transaction isolation, keeping a single version ...
