(service and application management). loader and unloader on the right side of the logic layer are the DATA import and export modules of infobright, that is, load data infile... And SELECT... The into file task is oriented to the massive data environment. Therefore, the data import and export module is an independent service and is not directly used by the mysql module. The infobright optimizer package of the logic layer is outside the mysql query optimizer, as will be mentioned below, because

The upper layer is service and application management, and the lower layer is the storage engine. The default storage engine of infobright is brighthouse.

BKJIA database channel has previously reported the world of Infobright in the column database. The overall architecture of Infobright is shown below: As shown in, Infobright adopts the same architecture as MySQL and is divided into two layers. The upper layer is service and application management, and the lower layer is the storage engine. The default storage engine of Infobright is brighthouse.
