Abstract: A database system may include a memory device that includes a least a portion to serve as a buffer cache and an array of persistent storage devices configured to store data of a database. The database system may monitor a frequency of data value associated with a first portion of data of the database stored in the buffer cache. The database system may maintain the first portion of data in the buffer cache in response to the frequency of data value associated with the first portion of data being greater than a frequency of data value associated with at least a portion of the data of the database stored in the array of persistent storage devices.
