Second, we continued reading in Write CF, scanned to KEY = 2_110, and we didn't find KEY = 2 in Lock CF.

At this time, since the values that have been committed are recorded in Write CF, and they are ordered from closest to farthest in time, KEY = 2_110 in Write CF is the most recent commit with a TSO of less than 120.

In this way, according to KEY = 2_110, VALUE = 100 in Write CF, we found the value KEY = 2_100, VALUE = Candy in DEFAULT CF.
