1. A computer-implemented method for optimizing data storage, comprising:

  • under the control of one or more computer systems configured with executable instructions,receiving information that includes at least;

    a transaction rate requirement for data stored on a storage system;

    a durability requirement for the data, the durability requirement including at least a maximum level of data loss per unit of time; and

    one or more operational characteristics of the storage system;

    determining, based at least in part on the transaction rate requirement, the durability requirement, and the one or more operational characteristics, an erasure coding scheme to be applied to the data;

    at a time after the erasure coding scheme is determined, modifying the erasure coding scheme applied to the data in response to a change in at least one of the transaction rate requirement, the durability requirement, or the one or more operational characteristics; and

    applying the modified erasure coding scheme to the data.
