Problems solved by technology

Queries are generally conditional retrievals. When searching through the API provided by HBase itself, if the relevant range of Rowkey cannot be set or the Rowkey can be specified directly, then HBase will scan the entire table, and HBase is designed for large data volumes. The total amount of data in a table can reach billions or even tens of billions of data, and the performance of full table scanning is very low.

Abstract

The invention discloses a data processing method, device and storage medium of a distributed database, wherein the method includes: generating a service characteristic bit sequence based on a service field value corresponding to the service field, and generating a bit sequence corresponding to the data to be processed according to the current time Identify the characteristic bit sequence, splicing the service characteristic bit sequence and the identification characteristic bit sequence to generate the row key Rowkey of the data to be processed. The method, device and storage medium of the present invention integrate business and query performance into one, can realize rapid generation of Rowkey, can use Rowkey to query, avoid full table scanning, and speed up query; use self-defined 64 base mask to generate Rowkey can ensure that the binary order generated by Rowkey is from small to large, which conforms to the sorting rules of HBase insertion order, and can quickly determine the range of Rowkey generation.

Description

technical field [0001] The present invention relates to the technical field of databases, in particular to a data processing method, device and storage medium of a distributed database. Background technique [0002] A distributed database is logically a unified whole, but physically it is stored on different physical nodes. There are many kinds of distributed databases, such as HBase and so on. HBase is a distributed column-oriented database built on the Hadoop file system. HBase is a database designed for large tables in enterprises with tens of billions of records. It has the characteristics of strong fault tolerance, high data reliability, and high performance. For columnar databases, data is stored according to columns. Generally, there is a concept of rowkey. Rowkey can uniquely identify a piece of data in a columnar database, and a piece of data can be quickly located by searching for a rowkey. Since HBase writes data in the ascending order of Rowkey, if the Rowkey o...
