AI Technical Summary

Benefits of technology

It describes how it allows users remotely access data stored within an Apache web site or databases through HTTP commands (hypertext transfer protocol). To achieve these technical benefits, there are two ways: 1) Encapling Java Interface with Jython programming that simplifies communication between clients and servers, allowing them to execute scripted queries against specific tables without having direct knowledge about their underlying structure.2） Using Python modules called HttpWriter which allow developers to write scripts directly onto SQL statements instead of compiling bytecodes themselves. These techniques help make writing more efficient when developing complex models like AJAX or XQuery interfaces.

Problems solved by technology

The technical problem addressed in this patents is how to allow large amounts of data stored over internet or machine networks efficiently accessible without being limited due to their structure.

Embodiment Construction

[0019] Referring to the accompanying drawings, a specific example is used to describe the process of remotely controlling the Hbase database of the present invention and the safe and stable Hbase database connection method of the present invention.

[0020] Proceed as follows:

[0021] 1) The client enters the Hbase server IP and the root node in zookeeper;

[0022] 2) The client calls the jdbc interface to establish a connection with the Hbase server. If the connection succeeds, the isConnection parameter is set to true. If the connection fails, the system exits;

[0023] 3) After the connection is successful, the user can initiate a series of Hbase operation requests on the client to remotely control Hbase. Refer to the attached figure 1 Describe the remote operation process of Hbase in detail:

[0024] a) The client enters the parameters of the database operation;

[0025] b) Determine whether isConnection is true, if isConnection is true, jump to step c), if isConnectio...

Abstract

The invention provides a connection method based on a python and an HBase jdbc, and belongs to the technical field of the IT communication industry. The method is achieved through the python language, an HBase database is remotely controlled at a client by packaging a jdbc interface of the HBase, DDL, DML and database operations such as HBase metadata query are achieved, codes used in the method are packaged into a python module so that the requirement for being connected with the HBase of other languages can be met, and remote call and development of the cross-platform HBase database are facilitated.
