Access management for a multi-endpoint data store

A method, comprising:

• performing, with one or more computing devices:
• receiving, at a data server from a client, a client data request for client data, wherein the client data is stored at a subset of data servers of a plurality of data servers included in a service provider network;
• determining a list of the subset of data servers based at least in part on a mapping of the client to the plurality of data servers, wherein the list comprises one or more identifiers corresponding to one or more endpoints for the subset of the data servers;
• generating a response to the client data request, wherein the response comprises a data portion and a server identifier portion, wherein the server identifier portion includes the one or more identifiers;
• and
• sending, to the client, the generated response.

A computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

• send, to a first endpoint of a plurality of endpoints for a service provider network, a client data request for client data, wherein the client data is stored in a subset of a plurality of data servers, and wherein the plurality of data servers comprising a first data server corresponding to the first endpoint;
• receive, from the first data server, a response to the client data request comprising a data portion and an endpoint identifier portion, wherein the endpoint identifier portion includes one or more identifiers to one or more other endpoints of the plurality of endpoints;
• identify the one or more other endpoints as having one or more other data servers that store at least some portion of the client data based on the one or more identifiers;
• access the one or more other endpoints based on the identifiers;
• and
• retrieve, from one or more data servers associated with the one or more other endpoints, additional client data.
