Generic metadata tags with namespace-specific semantics in a storage appliance
Disclosed is a method, apparatus, and system for a method for enforcing namespace-specific semantics based on object operations, the method comprising: detecting an operation performed on an object of a data storage system in a namespace associated with the object; determining whether additional operations on a tagset associated with the object are mandated by one or more semantics that are specific to the namespace based on the operation, a persona of the object in the namespace, and the one or more semantics; and in response to determining that additional operations are mandated by the one or more semantics, performing the additional operations mandated by the one or more semantics on the tagset.
1. A computer-implemented method for enforcing namespace-specific semantics
based on object operations, the method comprising:
detecting an operation performed on an object of a data storage system in a namespace associated with the object, wherein each object is associated with one or more namespaces;
determining whether additional operations on a tagset associated with the object are mandated by one or more semantics that are specific to the namespace based on the operation, a persona of the object in the namespace, and the one or more semantics, wherein each object is identifiable in each associated namespace by a respective unique persona, wherein the tagset includes system metadata tags generated automatically by the data storage system, and wherein the system metadata tags include virtual tags indicating a creation time of the object, a universal unique identifier of the object, and a sequence stamp of the object; and
in response to determining, based on a creation time of the object, a universal unique identifier of the object, and a sequence stamp of the object, that additional operations are mandated by the one or more semantics, performing the additional operations mandated by the one or more semantics on the tagset.
2. The method of claim 1 , wherein a semantic specific to a file-namespace mandates that when an MTree file object is snapshotted, a tagset associated with the MTree file object be snapshotted along with the MTree file object.
3. The method of claim 1 , wherein a semantic specific to a file-namespace mandates that when an MTree file object is replicated, a tagset associated with the MTree file object be replicated along with the MTree file object.
4. The method of claim 1 , wherein the tagset comprises standard metadata tags and the system metadata tags.
5. The method of claim 1 , wherein the object of the data storage system is a filesystem file.
6. The method of claim 1 , wherein the object of the data storage system is identifiable with a Universal Unique Identifier (UUID).
7. A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:
detecting an operation performed on an object of a data storage system in a namespace associated with the object, wherein each object is associated with one or more names paces;
determining whether additional operations on a tagset associated with the object are mandated by one or more semantics that are specific to the namespace based on the operation, a persona of the object in the namespace, and the one or more semantics, wherein each object is identifiable in each associated namespace by a respective unique persona, wherein the tagset includes system metadata tags generated automatically by the data storage system, and wherein the system metadata tags include virtual tags indicating a creation time of the object, a universal unique identifier of the object, and a sequence stamp of the object; and
in response to determining, based on a creation time of the object, a universal unique identifier of the object, and a sequence stamp of the object, that additional operations are mandated by the one or more semantics, performing the additional operations mandated by the one or more semantics on the tagset.
8. The non-transitory machine-readable medium of claim 7 , wherein a semantic specific to a file-namespace mandates that when an MTree file object is snapshotted, a tagset associated with the MTree file object be snapshotted along with the MTree file object.
9. The non-transitory machine-readable medium of claim 7 , wherein a semantic specific to a file-namespace mandates that when an MTree file object is replicated, a tagset associated with the MTree file object be replicated along with the MTree file object.
10. The non-transitory machine-readable medium of claim 7 , wherein the tagset comprises standard metadata tags and the system metadata tags.
11. The non-transitory machine-readable medium of claim 7 , wherein the object of the data storage system is a filesystem file.
12. The non-transitory machine-readable medium of claim 7 , wherein the object of the data storage system is identifiable with a Universal Unique Identifier (UUID).
13. A data processing system, comprising:
a processor; and
a memory coupled to the processor to store instructions, which when executed by the processor, cause the processor to perform operations, the operations including:
detecting an operation performed on an object of a data storage system in a namespace associated with the object, wherein each object is associated with one or more namespaces;
determining whether additional operations on a tagset associated with the object are mandated by one or more semantics that are specific to the namespace based on the operation, a persona of the object in the namespace, and the one or more semantics, wherein each object is identifiable in each associated namespace by a respective unique persona, wherein the tagset includes system metadata tags generated automatically by the data storage system, and wherein the system metadata tags include virtual tags indicating a creation time of the object, a universal unique identifier of the object, and a sequence stamp of the object; and
in response to determining, based on a creation time of the object, a universal unique identifier of the object, and a sequence stamp of the object, that additional operations are mandated by the one or more semantics, performing the additional operations mandated by the one or more semantics on the tagset.
14. The data processing system of claim 13 , wherein a semantic specific to a file-namespace mandates that when an MTree file object is snapshotted, a tagset associated with the MTree file object be snapshotted along with the MTree file object.
15. The data processing system of claim 13 , wherein a semantic specific to a file-namespace mandates that when an MTree file object is replicated, a tagset associated with the MTree file object be replicated along with the MTree file object.
16. The data processing system of claim 13 , wherein the tagset comprises standard metadata tags and the system metadata tags.
17. The data processing system of claim 13 , wherein the object of the data storage system is a filesystem file.
18. The data processing system of claim 13 , wherein the object of the data storage system is identifiable with a Universal Unique Identifier (UUID).
