US 2019/0155536 A1 · SYSTEMS AND METHODS FOR MIGRATING DATA

Abstract

According to various aspects of the present disclosure, methods, systems, and media for data migration are provided. In some embodiments, 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 in communication with the computer-readable storage medium, wherein when executing the set of instructions, the at least one processor is directed to: query data in a data storage system comprising a plurality of slave nodes; determine, from a plurality of data records in the slave nodes, at least one candidate data record that satisfies a first condition; identify, from the slave nodes, at least one candidate slave node that satisfies a second condition; and in response to determining that the number of the at least one candidate slave node is not less than a threshold value, migrate the candidate data record to a target slave node.

Dependent claims

A system, comprising:

at least one computer-readable storage medium including a set of instructions for migrating data records;
and
at least one processor in communication with the computer-readable storage medium, wherein when executing the set of instructions, the at least one processor is directed to:
query data in a data storage system comprising a plurality of slave nodes;
determine, from a plurality of data records in the plurality of slave nodes, at least one candidate data record that satisfies a first condition;
identify, from the plurality of slave nodes, at least one candidate slave node that satisfies a second condition;
and
in response to determining that the number of the at least one candidate slave node is not less than a threshold value, migrate the at least one candidate data record to at least one target slave node.

A non-transitory computer-readable medium, comprising at least one set of instructions for migrating data records, wherein when executed by at least one processor, the at least one set of instructions directs the at least one processor to:

query data in a data storage system comprising a plurality of slave nodes;
determine, from a plurality of data records in the plurality of slave nodes, at least one candidate data record that satisfies a first condition;
identify, from the plurality of slave nodes, at least one candidate slave node that satisfies a second condition;
and
in response to determining that the number of the at least one candidate slave node is not less than a threshold value, migrate the at least one candidate data record to at least one target slave node.
