In this blog we will explore how to setup a docker compose file in order to migrate from MySQL 5.7 to the latest MariaDB.
In the next blog we will explain how to setup a docker compose file to migrate from MySQL 8.0 to MariaDB.
The steps to migrate from MySQL 5.7 to MariaDB are:
- Start container by running docker-compose file
- Use the MySQL data directory and start MariaDB with MARIADB_AUTO_UPGRADE=1
Let’s explore each step.
1. Start MySQL
The MySQL container is started using the following docker-compose file.

Remember our open letter, Looking for MySQL 5.7 or 8.0 guinea pigs?
We caught a nice German guinea pig!
We caught a nice guinea pig, a German one, from Hannover. They are currently using MySQL 5.7 (as was our prime wish), and they will be doing a live migration to MariaDB 10.11. They have 1.000.000.000 queries a day, their database size is 412 GB, and our goal is to the migration of the production data in less than five minutes – during our MariaDB Migration Workshop at our pre-FOSDEM event on Friday 2 Feb 2024.

Dear users of MySQL 5.7 (or 8.0)!
Are you interested in getting help migrating to MariaDB 10.6 or 10.11, the latest long-term support releases? Are you coming to Brussels for FOSDEM in February? Do you have an open attitude, not minding to show a bit of dirty laundry in front of other users?
Then you may be a perfect candidate for our MariaDB Migration Workshop at our pre-FOSDEM event on Friday 2 Feb 2024. The workshop will be led by none other than the father of both MySQL Server and MariaDB Server, namely Michael “Monty” Widenius.

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.

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:
- Dump Oracle data to CSV and load data in MariaDB.
- 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.
