User-specific data manipulation system for object storage service based on user-submitted code

Abstract:

Systems and methods are described for modifying input and output (I/O) to an object storage service by implementing one or more owner-specified functions to I/O requests. Different data manipulation functions can be placed in different I/O paths depending on the request method or user access level. For example, a user having full access may be returned the unaltered version of the object, whereas a user having modified or reduced access may be returned a modified or redacted version of the object. In this manner, owners of the object collection are provided with greater control over how the object collection is accessed.
