Embodiment Construction

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0056]The principle of loading text table data in other existing databases is relatively simple, that is, each SQL execution thread initializes its own file reader. The file reader is responsible for reading string data line by line from the text file and parsing it into a line of structured memory data; if the text table is associated with a file list (more than 1 text file), the file read The reader reads each file in turn; if multiple SQL execution threads ...

Abstract

The invention discloses a method and device for loading database text table data. The method includes the steps that a to-be-loaded target text table in a database is determined, wherein the target text table comprises N text files, and N is a positive integer larger than or equal to 1; N first queues are established in a memorizer, and a one-to-one mapping corresponding relation exists between each first queue and the corresponding text file; each text file is subjected to read operation, and then data read out from each text file is written in the corresponding first queue; M second queues are established in the memory, wherein M is a positive integer larger than or equal to 1; the data is sequentially read out from the N first queues, and the read-out N data is simultaneously copied in each second queue, wherein the data in the M second queues can be read respectively and used for corresponding concurrence requirements.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a method and device for loading text table data in a database. Background technique [0002] With the further improvement of the centralization of network operation and maintenance, the application functions of network management integration continue to increase, the amount of data that needs to be managed by operation and maintenance is also rapidly increasing, and the demand for multi-dimensional reading of data is also emerging. [0003] However, when the existing traditional databases face large concurrency requirements of orders of magnitude, they usually provide data loading for each concurrent task in turn, so there will be a large operating load. Insufficient parallel processing capability of high-level data; or providing data loading for each concurrent task through memory at the same time, but there will be a problem that the data loading efficiency will be greatly re...
