Document Type and Number:
WIPO Patent Application WO/2018/014613
Kind Code:
A1
Abstract:
Methods, systems, and media for data migration are provided. The systems may include: at least one computer-readable storage medium including a set of instructions for migrating data records; and at least one processor (220) in communication with the computer-readable storage medium, wherein when executing the set of instructions, the at least one processor (220) is directed to: query data in a data storage system (100) comprising a plurality of slave nodes (130); determine, from a plurality of data records in the slave nodes (130), at least one candidate data record that satisfies a first condition; identify, from the slave nodes (130), at least one candidate slave node (130-1, 130-2, 130-3,…, 130-N) that satisfies a second condition; and in response to determining that the number of the at least one candidate slave node (130-1, 130-2, 130-3,…, 130-N) is not less than a threshold value, migrate the candidate data record to a target slave node (130-1, 130-2, 130-3,…, 130-N).
