Systems and methods for offloading data processing tasks using in-storage code execution are disclosed. For example, a data storage system including one or more processors, a non-transitory storage medium, and a storage logic executable by the one or more processors to perform operations including: receiving portable code configured to perform a data processing offload task, the portable code comprising one or more translatable, hardware-agnostic instructions for processing data stored on the storage medium; translating and executing the one or more translatable, hardware-agnostic instructions of the portable code to perform the data processing offload task using a translation and execution engine disposed in the storage logic; determining that use of the portable code has concluded; and responsive to determining that use of the portable code has concluded, releasing the portable code.
