Index hot loading method and device on basis of advertisement putting

The embodiment of the invention provides an index hot loading method and device on the basis of advertisement putting. The index hot loading method on the basis of advertisement putting includes the steps of performing region segmentation on a directory bitmap file to obtain a plurality of index blocks, wherein the directory bitmap file is an advertisement plan index table formed by a plurality ofadvertisement materials and a plurality of advertisement conditions, and each index block includes different advertisement plans; when the directory bitmap file is updated, successively re-constructing a backup index block corresponding to each index block; successively updating the corresponding index block in the directory bitmap file by using each backup index block. By performing region segmentation on the directory bitmap file, the index blocks are obtained so that the memory usage can be greatly reduced each time when a backup index block is reconstructed, after the construction is completed, the corresponding
