ATOMIC UPDATE OPERATIONS IN A DATA STORAGE SYSTEM

摘要

Technology is disclosed for performing atomic update operations in a storage system (“the technology”). The technology can receive an update command to update a value associated with a key stored in the storage system as a function of an input value; store the input value in a log stored at the storage system but not updating the value stored in the storage system; and update the value associated with the key with the received input values value based on the a function to generate an updated value, the updating occurring asynchronously with respect to receiving the update command.

1. A method performed by a computing system, comprising:
receiving, at a storage system from a computer system, an update command to update a value associated with a key stored in the storage system as a function of an input value; storing, by the storage system, the input value in a log stored at the storage system but not updating the value stored in the storage system; and updating, by the storage system, the value associated with the key with the received input value based on a function to generate an updated value, the updating occurring asynchronously with respect to receiving the update command.
