METHOD AND APPARATUS FOR OPTIMIZING DATA ACCESS, METHOD AND APPARATUS FOR OPTIMIZING DATA STORAGE

摘要

Disclosed are a method and an apparatus for optimizing data access, and a method and an apparatus for optimizing data storage. The method for optimizing data access comprises: a main controller receiving a request of a user for accessing a data table in HBASE, the request carrying data input range information, and the data input range information comprising a plurality of data input ranges; determining input block information according to region information of the data table and the data input range information; determining the number of Map tasks according to the input block information; distributing, according to the number of the Map tasks, data in the data table read from a processor; and returning the data read from the processor to the user.
