Problems solved by technology

In the existing technology, the index is also built when the data is loaded, so as the amount of loaded data increases, the loading speed becomes smaller and smaller. When inserting a piece of data, these indexes need to be maintained, so the loading speed is constantly declining

Embodiment Construction

[0024] This embodiment is implemented using the relational database oracle 10g, and other relational databases are also applicable; the operating system adopts RedFlag DC 5.0; the hardware environment adopts DELL 2850 standard server, and the specific configuration is shown in Table 1, and an index is established on the table according to business requirements. In addition, in order to ensure the legitimacy of the data, it is necessary to establish a primary key index on the temporary table; under the above conditions, the loading effect of directly entering the ordinary table and directly entering the temporary table plus indexing and transferring data is shown in Table 2. , and at the same time query and compare the accumulated 100 million pieces of data according to a known condition, as shown in Table 3. From the data in the table, it can be seen that on the basis of relatively stable query speed, the loading speed increases by about 10 times.

Abstract

The invention belongs to the computer field, in particular relating to a method for processing mass data loading and inquiry. The invention uses a temporary list with proper granularity to buffer data of various time slices; no index is established on the temporary list or a master key index is established on the temporary list; after the data of various time slices is processed, indexes are established unitarily for the data of the time slices and then the data is transferred to a partition table. The method for processing mass data loading and inquiry improves the inquiry speed by combination of the data of the partition list according to business requirements, is only related to the data quantity in the buffer time slices and can meet the high-speed mass data loading environment and the business requirements provided with related inquiries.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a method for loading and querying massive data. Background technique [0002] With the rapid development of enterprise informatization and the Internet, massive data processing has become a top priority, especially in the telecommunications industry and the Internet industry. Some special methods must be used to process massive data. Based on this, the present invention proposes a method capable of quickly loading massive amounts of data and enabling queries at the same time. [0003] Usually, the way to improve query speed is to build indexes and trade space for time. This has little or no impact on small batches of data. But when the amount of data is very large, the contradiction is more obvious, seriously affecting the loading speed. Of course, if better hardware is used, there will be a great improvement. For example, using a supercomputer is much faster than using a ...
