Problems solved by technology

However, in the actual application of big data developed today, users may tend to use multiple key values ​​for multi-dimensional retrieval. At this time, existing solutions can only scan the entire data by running a background batch task set and get the search results
However, this type of solution lacks real-time performance, and the newly stored data tuples cannot be retrieved in time, and must wait until the background batch task completes the scan before being retrieved.

Abstract

The invention provides a big data retrieval method based on cloud computing. The method includes the steps that an index structure of a cloud storage system is divided into the two levels of a main index and local indexes; data content is stored into the local indexes; indexes are built for metadata issued by all the local indexes in the main index through a chained queue; retrieval is achieved through correlation of the metadata. The data retrieval method is provided, retrieval in multiple modes is effectively supported, expandability is high, concurrency of the main index is improved, dynamic real-time performance is good, and it is guaranteed that overall loads of an index structure are balanced.

Description

technical field [0001] The invention relates to data processing, in particular to a cloud computing-based big data retrieval method. Background technique [0002] Cloud computing systems can provide massive storage and reliable services, so they are increasingly valued. In the cloud infrastructure, thousands of interconnected computers form a "cloud" that provides services. A large number of users can share this "cloud" at the same time, and tailor the required resources according to their actual needs. . As an important part of cloud data processing, most of the current cloud storage systems use distributed hash tables to build indexes, and data is organized into key-value pairs. Therefore, this type of cloud storage system only supports keyword search and accesses data through point search. However, in the actual application of big data developed today, users may tend to use multiple key values ​​for multi-dimensional retrieval. At this time, existing solutions can only...
