Patent ID: 10740246

Abstract:
A system in which first header data, second header data, a first logical array and a second logical array are stored in volatile random access memory. Each array position of the first logical array represents an identifier of a database column value and stores an offset value associated with an array position of the second logical array, and each array position of the second logical array stores a row position of the database column value. A memory size associated with the first header data, the second header data, the first logical array and the second logical array is determined, a first memory block of a non-volatile random access memory is allocated based on the determined memory size, an address of the non-volatile 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 logical array and a binary copy of the second logical array are written at the address of the non-volatile random access memory.
