Method, electronic device, and computer program product for cross-regional data searching

An electronic device, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and having instructions stored therein, wherein the instructions, when executed by the at least one processor, cause the device to perform actions comprising:
• acquiring a data identifier of target data in response to receiving a searching request for the target data at a first node;
• determining, based on the data identifier, a second node storing metadata of the target data, wherein both the first node and the second node are located in a first region, and the metadata comprises the data identifier;
• and
• determining, based on the metadata, a third node storing the target data, wherein the third node is located in a second region different from the first region.

A computer program product tangibly stored on a non-transitory computer-readable medium and comprising machine-executable instructions, wherein the machine-executable instructions, when executed by a machine, cause the machine to perform a method for cross-regional data searching, the method comprising:

• acquiring a data identifier of target data in response to receiving a searching request for the target data at a first node;
• determining, based on the data identifier, a second node storing metadata of the target data, wherein both the first node and the second node are located in a first region, and the metadata comprises the data identifier;
• and
• determining, based on the metadata, a third node storing the target data, wherein the third node is located in a second region different from the first region.
