Methods, apparatuses, and computer program products for management of data deletion requests based on geographically distributed data

1. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by a processor, perform a method for deletion of geographically distributed data within a group-based communication system, the method comprising the steps of:

receiving, from a client device, a message deletion request comprising a message identifier;

locating a first repository row comprising message metadata and residency token data associated with the message identifier within a local repository physically located in a first geographic area;

upon locating the first repository row, initiating a local repository row erasure operation by which contents of the first repository row are erased from the local repository; and

upon completion of the local repository row erasure operation, transmitting a data residency deletion request to a geographic data residency server associated with the residency token data, the data residency deletion request comprising the residency token data and indicating an expiration window of a data residency repository row associated with the residency token data, and

wherein, upon lapsing of the expiration window, the data residency deletion request is configured to initiate an erasure operation by which the contents of the data residency repository row are erased from a geographic data residency repository comprising the data residency repository row,

the geographic data residency repository being physically located within a second geographic area distinct from the first geographic area.

2. The one or more non-transitory computer-readable media of claim 1 , wherein the geographic data residency server is physically located within a third geographic area.

3. The one or more non-transitory computer-readable media of claim 1 , wherein the first geographic area is subject to a first data storage policy and the second geographic area is subject to a second data storage policy different from the first data storage policy.

4. The one or more non-transitory computer-readable media of claim 1 , wherein the residency token data comprises one or more of the message identifier, a storage location identifier, or a message encryption key.

5. The one or more non-transitory computer-readable media of claim 1 , wherein the message deletion request comprises a plurality of message identifiers.

6. The one or more non-transitory computer-readable media of claim 5 , wherein a first message identifier of the plurality of message identifiers is associated with a first data residency row stored in the geographic data residency repository in the second geographic area, and wherein a second message identifier of the plurality of message identifiers is associated with a second data residency row stored in another geographic data residency repository in a third geographic area distinct from the first geographic area and the second geographic area.

7. The one or more non-transitory computer-readable media of claim 1 , wherein the method further comprises the step of:

in an instance where a data residency deletion confirmation is not received within a deletion confirmation window, enqueuing a subsequent data residency deletion request comprising the residency token data to be transmitted to the geographic data residency server.

8. A method for deletion of geographically distributed data within a group-based communication system, the method comprising the steps of:

receiving, from a client device, a message deletion request comprising a message identifier;

locating a first repository row comprising message metadata and residency token data associated with the message identifier within a local repository physically located in a first geographic area;

upon locating the first repository row, initiating a local repository row erasure operation by which contents of the first repository row are erased from the local repository; and

upon completion of the local repository row erasure operation, transmitting a data residency deletion request to a geographic data residency server associated with the residency token data, the data residency deletion request comprising the residency token data and indicating an expiration window of a data residency repository row associated with the residency token data, and

wherein, upon lapsing of the expiration window, the data residency deletion request is configured to initiate an erasure operation by which the contents of the data residency repository row are erased from a geographic data residency repository comprising the data residency repository row,

the geographic data residency repository being physically located within a second geographic area distinct from the first geographic area.

9. The method of claim 8 , wherein the geographic data residency server is physically located within a third geographic area.

10. The method of claim 8 , wherein the first geographic area is subject to a first data storage policy and the second geographic area is subject to a second data storage policy different from the first data storage policy.

11. The method of claim 8 , wherein the residency token data comprises one or more of the message identifier, a storage location identifier, or a message encryption key.

12. The method of claim 8 , wherein the message deletion request comprises a plurality of message identifiers.

13. The method of claim 12 , wherein a first message identifier of the plurality of message identifiers is associated with a first data residency row stored in the geographic data residency repository in the second geographic area, and wherein a second message identifier of the plurality of message identifiers is associated with a second data residency row stored in another geographic data residency repository in a third geographic area distinct from the first geographic area and the second geographic area.

14. The method of claim 8 , further comprising the step of:

in an instance where a data residency deletion confirmation is not received within a deletion confirmation window, enqueuing a subsequent data residency deletion request comprising the residency token data to be transmitted to the geographic data residency server.

15. A system for performing deletion of geographically distributed data within a group-based communication system, the system comprising:

a client device;

a local repository physically located in a first geographic area;

a geographic data residency repository physically located in a second geographic area distinct from the first geographic area;

a processor programmed to perform a method for deletion of geographically distributed data, the method comprising the steps of:

receiving, from the client device, a message deletion request comprising a message identifier;

locating a first repository row comprising message metadata and residency token data associated with the message identifier within the local repository;

upon locating the first repository row, initiating a local repository row erasure operation by which contents of the first repository row are erased from the local repository; and

upon completion of the local repository row erasure operation, transmitting a data residency deletion request to a geographic data residency server associated with the residency token data, the data residency deletion request comprising the residency token data and indicating an expiration window of a data residency repository row associated with the residency token data, and

wherein, upon lapsing of the expiration window, the data residency deletion request is configured to initiate an erasure operation by which the contents of the data residency repository row are erased from the geographic data residency repository comprising the data residency repository row.

16. The system of claim 15 , wherein the geographic data residency server is physically located within a third geographic area.

17. The system of claim 15 , wherein the first geographic area is subject to a first data storage policy and the second geographic area is subject to a second data storage policy different from the first data storage policy.
