System and method for object store federation

A non-transitory computer readable storage medium comprising instructions stored thereon that, when executed by a processor, cause the processor to:

• receive a request to create a bucket in an object store federation including a plurality of object stores including a first object store and a second object store;
• and
• in response to receiving the request to create the bucket:
• create global metadata for the bucket to be created, wherein the global metadata is part of a global namespace for the object store federation;
• write, to the first object store, a first mapping that maps an identifier of global metadata to the second object store where the bucket is to be created, wherein the first object store includes a first local namespace and the second object store includes a second local namespace;
• create the bucket in the second object store;
• create local metadata of the bucket in the second object store, wherein the local metadata is part of the local namespace of the second object store;
• write, to the second object store, a second mapping that maps the identifier of global metadata to local metadata;
• replicate, to the second object store, the first mapping of the global metadata to the second object store;
• and
• update the global metadata to indicate that the bucket is created in the second object store.

A computer-implemented method comprising:

• receiving, by a processor, a request to create a bucket in an object store federation including a plurality of object stores including a first object store and a second object store;
• and
• in response to receiving the request to create the bucket:
• creating, by the processor, global metadata for the bucket to be created, wherein the global metadata is part of a global namespace for the object store federation;
• writing, by the processor, to the first object store, a first mapping that maps the global metadata to the second object store where the bucket is to be created, wherein the first object store includes a first local namespace and the second object store includes a second local namespace;
• creating, by the processor, the bucket in the second object store;
• creating, by the processor, local metadata of the bucket in the second object store, wherein the local metadata is part of the local namespace of the second object store;
• writing, by the processor, to the second object store, a second mapping that maps the identifier of global metadata to local metadata;
• replicating, by the processor, to the second object store, the first mapping of the global metadata to the second object store;
• and
• updating, by the processor, the global metadata to indicate that the bucket is created in the second object store.
