Abstract

A system includes storage, in a volatile random access memory, of a first data block comprising an array of distinct values of a database table column, and first header data comprising a first pointer to the first data block, determination of a memory size associated with the first header data and the first data block, allocation of a first memory block of the non-volatile random access memory based on the determined memory size, determination of an address of the non-volatile random access memory associated with the allocated first memory block, and writing of an indicator of the number of distinct values of the array and a binary copy of the first data block at the address of the non-volatile random access memory.
