Optimizing geometry based on workload characteristics

A computer-implemented method, comprising:

• tracking input/output operations of a first volume provided by a data storage service to a customer of a computing resource service provider, wherein the first volume is a logical storage space, comprised of a set of data storage partitions within a data storage system according to a first partitioning scheme, in which data objects may be stored and wherein the first volume is attached to a computer system instance of a computer system service such that an operating system of the computer system instance recognizes the first volume and is able to perform the input/output operations with the first volume;
• analyzing the tracked input/output operations to determine an input/output profile for the first volume;
• determining, based at least in part on the determined input/output profile, to change the first partitioning scheme;
• determining a second partitioning scheme based at least in part on the determined input/output profile to fulfill a set of optimization criteria that at least specifies a size and number of partitions for a set of persistent computer-readable storage media, wherein the set of optimization criteria reduces an amount of resources of the data storage service consumed while meeting or exceeding a service-level agreement threshold;
• provisioning a second volume comprised of the size and number of partitions specified by the second partitioning scheme;
• copying the data objects from the first volume and the first partitioning scheme to the second volume and the second partitioning scheme;
• detaching the first volume from the computer system instance;
• and
• attaching the second volume to the computer system instance such that the operating system of the computer system instance recognizes the second volume and is able to perform the input/output operations with the second volume and the second partitioning scheme instead of the first volume and the first partitioning scheme.
