Connect SE JDBC table type: Accessing Tables From Another DBMS

In this blog we will show how to access MySQL and MariaDB DBMS tables from MariaDB Server. For that we will use Connect Storage Engine (SE), which supports different table types options. In this case we will use the JDBC table type. To use the JDBC table type we need to specify it in the CREATE TABLE definition for Connect SE and we need the Java connector for the DBMS we are accessing. For demonstration purposes we will use containers, but this will work if the servers are running in VMs or bare-metal. Just make sure the machines can access each other via TCP/IP.

Data migration from Oracle to MariaDB with Docker and Connect SE: A Step-by-Step Guide

In this blog we are going to learn how to migrate data from Oracle to MariaDB.

To begin, we’ll learn the basics about Oracle database to have an understanding about the steps that are done on the demo example. After, we will create a table in Oracle and migrate it to MariaDB.

To migrate data from Oracle there are 2 ways:

  1. Dump Oracle data to CSV and load data in MariaDB.
  2. Use the Connect Storage Engine to create or insert into a table from Oracle’s source definition.

For demonstration, we are going to use a docker container with an Oracle Express Edition (XE) image.

Via SpamExperts:

SpamExperts has their own anti-spam filtering cloud which is provided as a software-as-a-service (SaaS) model. In addition they have an e-mail security product which they install, update and monitor on-site. Most of SpamExperts’ anti-spam technology has been developed in-house and makes extensive use of the MySQL database. All clients contribute in real-time to their filtering effectiveness, so they have many different data flows that are handled by MySQL. Replication is used to synchronize the data between the systems in a cluster and to push data feeds in real-time. The SaaS cloud is replicated across four countries for redundancy, whereas client installations spread the data retrieval around the globe.
