Data fragmentation tuning and candidacy persistence

Abstract:

A method for implementing defragmentation of a data area is provided. The method includes receiving a data change event for the data area and determining, whether the data area has exceeded a defragment threshold based on a defragment threshold value. The method may further include adding the data area to a candidacy list when the data area is determined to have exceeded the defragment threshold based on the defragment threshold value. The method may also include defragmenting the data area when the data area is determined to have exceeded the defragment threshold based on the defragment threshold value and removing the data area from the candidacy list following the determination.
