Abstract

Claims (50)

1 . An apparatus comprising a processor and a memory, the memory having programmed instructions that, when executed by the processor, cause the apparatus 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 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;

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 global metadata to the 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.

2 . The apparatus of claim 1 , the memory having the programmed instructions that, when executed by the processor, further cause the apparatus to:

receive a request to provide a list of buckets that are created within the first object store or the second object store; and

spawn remote procedure calls to each of the first object store and the second object store to provide a list of buckets of the respective object store.

3 . The apparatus of claim 1 , wherein the first mapping is replicated using a consensus protocol.

4 . The apparatus of claim 1 , wherein the first mapping is replicated at an application level or a virtual node level.

5 . The apparatus of claim 1 , wherein the first object store includes a first tenant and the second object store includes a second tenant.

6 . 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.

7 . The non-transitory computer readable storage medium of claim 6 , comprising the instructions that, when executed by the processor, further cause the processor to:

receive a request to provide a list of buckets that are created within the first object store or the second object store; and

spawn remote procedure calls to each of the first object store and the second object store to provide a list of buckets of the respective object store.

8 . The non-transitory computer readable storage medium of claim 6 , wherein the first mapping is replicated using a consensus protocol.

9 . The non-transitory computer readable storage medium of claim 6 , wherein the first mapping is replicated at an application level or a virtual node level.

10 . The non-transitory computer readable storage medium of claim 6 , wherein the first object store includes a first tenant and the second object store includes a second tenant.

11 . 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.

12 . The computer-implemented method of claim 11 , further comprising:

receiving, by the processor, a request to provide a list of buckets that are created within the first object store or the second object store; and

spawning, by the processor, remote procedure calls to each of the first object store and the second object store to provide a list of buckets of the respective object store.

13 . The computer-implemented method of claim 11 , wherein the first mapping is replicated using a consensus protocol.

14 . The computer-implemented method of claim 11 , wherein the first mapping is replicated at an application level or a virtual node level.

15 . The apparatus of claim 3 , wherein the instructions cause the apparatus to write the first mapping to a set of object stores using the consensus protocol, wherein the set of object stores comprises core members that run a distributed consensus service to provide fault tolerance.

16 . The non-transitory computer readable storage medium of claim 8 , wherein the instructions cause the processor to write the first mapping to a set of object stores using the consensus protocol, wherein the set of object stores comprises core members that run a distributed consensus service to provide fault tolerance.

17 . The computer-implemented method of claim 13 , further comprising replicating the first mapping to a set of object stores using the consensus protocol, wherein the set of object stores comprises core members that run a distributed consensus service to provide fault tolerance.
