Generating and compressing universally unique identifiers (UUIDs) using counter having high-order bit to low-order bit

摘要

A computer-based method and system for generating and compressing a plurality of universally unique identifiers (UUIDs). The bits of the UUIDs are ordered from left to right. The system maintains a counter with bits ordered from a high-order bit to a low-order bit. To generate a UUID, the system increments the counter. The system then sets the right-most bits of the UUID to a node identifier, sets the next right-most bits of the UUID to a clock sequential/variant value, and sets the left-most bits of the UUID to the bits of the counter wherein the left-most bit of the UUID is set to the lowest-order bit of the counter so that sequentially generated UUIDs tend to have the same values in their right-most bits. The system then compresses these UUIDs using a suffix compression technique.
