Patent ID: 10719450

Abstract:
A system in which a volatile random access memory stores first header data, second header data, a first logical array in a first contiguous memory block and a second logical array in a second contiguous memory block. Each array position of the first logical array stores a database column value, and each array position of the second logical array stores an indication of a number of consecutive occurrences of a database column value. The first header data includes a first pointer to the first memory block, and the second header data includes a second pointer to the second memory block. A memory size is determined associated with the first header data, the second header data, the first memory block, and the second memory block, a first memory block of the non-volatile random access memory is allocated based on the determined memory size, an address of the random access memory associated with the allocated first memory block is determined, and a portion of the first header data, a portion of the second header data, a binary copy of the first memory block and a binary copy of the second memory block are written at the address of the random access memory.
