CONTROLLING MIRRORING OF TABLES BASED ON ACCESS PREDICTION

摘要

A system for managing a plurality of storage devices that are configured to store a database. The system includes an access instruction acquiring unit configured for acquiring an access instruction to access the database. The system also includes a predicting unit configured for predicting a table to be accessed in response to the acquired access instruction. The system further includes a relocation unit configured for mirroring the table predicted by the predicting unit, the mirroring between the plurality of storage devices.

1. A system for managing a plurality of data storage comprising a plurality of volumes storing a database, the system comprising:
at least one processor; and at least one memory storing computer-executable instructions, wherein the at least one processor is configured to access the at least one memory and execute the computer-executable instructions to:
identify an access instruction for accessing the database;determine that a table is to be accessed based at least in part on the access instruction;determine that a first one or more volumes of the plurality of volumes contains the table;cancel mirroring of a second one or more volumes of the plurality of volumes from first data storage of the plurality of data storage to second data storage of the plurality of data storage; andinitiate mirroring of the first one or more volumes from the first data storage to the second data storage.
