System and method for providing a committed throughput level in a data store

A system, comprising:

• a plurality of computing nodes, each comprising at least one processor and memory, wherein the plurality of computing nodes is configured to implement a data storage service;
• wherein the data storage service provides a service interface through which service requests are received from storage service clients;
• wherein the data storage service maintains a plurality of tables in a data store on behalf of one or more storage service clients, and wherein maintaining the plurality of tables comprises storing table data in each of one or more partitions on respective computing nodes in the data store;
• wherein the data storage service is configured to receive a service request to create a table in the data store, wherein the request specifies selection of a committed throughput model for servicing requests directed to the table from among two or more throughput models supported by the data storage service, and wherein the request specifies a committed throughput level for the table;
• wherein, in response to receiving the request, the data storage service is configured to reserve sufficient resources for the table to meet the specified committed throughput level;
• wherein the data storage service is configured to receive a service request to increase the committed throughput level for the table, wherein the request specifies an increased committed throughput level for the table;
• and
• wherein, in response to receiving the request to increase the committed throughput level for the table, the data storage service is configured to increase the resources reserved for the table to meet the increased committed throughput level for the table.
