Magic xpa Cache Internal Implementation (Magic xpa 2.x)

Every row that Magic xpa reads is inserted into the cache. In addition, any modification, deletion, or insertion of new rows, is also placed in the cache. Whenever a row that already exists is reread by Magic xpa, it will supersede the previous value. If a row that does not exist in the cache is read, the Magic xpa Cache automatically places it in the cache. If the cache is full, an LRU (Least Recently Used) algorithm is used to determine which element is to be dumped from the cache.

The use of the LRU mechanism ensures that data that is read more frequently will have a lower chance of being swapped out of the cache.
