Abstract:
1. A computer-implemented method of determining a storage location for a data item, the method comprising: providing a first data storage location and a second data storage location, the first data storage location having an appreciably faster access speed than the second data storage location, wherein the first and second data storage locations are primary storage locations that provide persistent storage; accessing a score associated with the data item, the score being calculated by a computer device based on a frequency of access of the data item; selecting only one of the first data storage location or the second data storage location based on a value of the score associated with the data item with respect to scores of other data items being stored, wherein the data item is stored in only one of the first data storage location or the second data storage location at any point in time; periodically re-calculating the scores associated with the data items in a table, wherein the score is accessed from a score table of data items; and in response to the re-calculating of the scores, causing a change in the selecting of the one of the first data storage location or the second data storage location, removing the data item from a current storage location and adding the removed data item to a newly selected storage location.
