Problems solved by technology

[0005] In the existing technical solutions, 1) the index generally coexists with the original data, which is not applicable to the scheme-on-read mechanism in the big data environment; 2) the index usually points to the specific location of each record, and the granularity is too fine to support massive Data indexing, and it is difficult to support an efficient batch deletion mechanism

Abstract

The invention provides a data indexing method and equipment. The data indexing method comprises the steps of building index data according to column values of multiple files; when retrieving conditions are received, determining the column values which need to be retrieved; according to the determined column value, conducting retrieving in the column values to obtain a file including the column values which need to be retrieved. By means of the data index method and equipment, by building the index data, when the retrieving conditions are received, the file including the column values which need to be retrieved can be quickly retrieved, and massive data indexing is supported; meanwhile, a storing structure of original data is not influenced, and the data indexing method can adapt to different original data formats.

Description

technical field [0001] The invention relates to the field of data storage and management, in particular to a data indexing method and equipment. Background technique [0002] With the development of informatization and the advent of the era of big data, the amount of data is growing explosively. In order to support the rapid retrieval of data in a massive data environment, the design of data index has become a crucial link. [0003] In a massive data environment, due to the large amount of data, usually only the recent data is indexed and cached, so as time goes by, there will be a large number of addition and deletion operations on the index structure; on the other hand, due to the excessive amount of data Large, the design of the index structure needs to maximize the memory utilization. In traditional relational data, structures such as B+Tree are usually used to realize the data index structure, but this method has problems such as high memory usage and low index deletio...
