Abstract

A system, method, and computer program product are provided for migrating interdependent data objects from a first device to a second device. In use, at least one first data object to be migrated from a first device to a second device associated with a target code is received. Further, it is determined that the second device associated with the target code requires at least one second data object to be present at least one of before the at least one first data object or at a same time as the at least one first data object. Additionally, the at least one first data object to be migrated from the first device to the second device associated with the target code is stored in a cache. Furthermore, an interdependency event associated with the at least one first data object and the at least one second data object is detected. In response to detecting the interdependency event, the at least one second data object to be migrated from the first device to the second device associated with the target code is received. Moreover, the at least one first data object and the at least one second data object are automatically sent to the second device associated with the target code, in response to receiving the at least one second data object.

11. The computer program product of claim 1, further comprising computer code for associating at least one source key with the at least one second data object.

12. The computer program product of claim 11, further comprising computer code for causing publishing of the at least one source key associated with the at least one second data object.

13. The computer program product of claim 12, wherein the computer program product is operable such that publishing of the at least one source key associated with the at least one second data object is utilized to detect the creation of the at least one second data object.

14. The computer program product of claim 13, further comprising computer code for determining that the first data object can be released from the cache, based on detecting the creation of the at least one second data object.

15. The computer program product of claim 14, further comprising computer code for automatically sending the first data object and the at least one second data object to the second device associated with the target code, in response to determining that the first data object can be released from the cache.
