We are looking to optimize our database performance by delaying the output of frequently used object. In the following chart, the object X is frequently accessed by many transactions, and we must repeatedly read X from the disk to memory, update the value of X in memory, and then flush the updated value of X to the disk. Say X is branch balance: T1: ... update X... T2: update X... www T3:... update X... T4:... update X... ♥ Actions: write X output X write X output X write X output X write X output X As you can imagine, this is very inefficient because it results in a lot of I/Qs. Please briefly describe a better workflow to reduce the number of I/Qs for frequently accessed values. Hint: think about what the redundant operations are in the above figure and consider removing them.
