CONNECT STORAGE ENGINE Archives

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 see how to create a link to a remote server and use it to access multiple tables at once.
In the previous blog we have seen how to establish a remote connection between Docker containers.
The way we did it was to specify the connection string to reference a single table only.
But what if we need more tables, what if need a whole database?

The solution is to link to a remote database with the CREATE SERVER statement.
A link obtained this way can be passed to the CREATE TABLE statement of a storage engine (SE) to make a connection where using the table discovery feature SE will find out about the table fields and create the table.

CONNECT is a storage engine (SE) plugin used to access external, local or remote data. In this blog we are going to show how to install the CONNECT storage engine in a Docker container and how to share JSON data between containers.

Enabling CONNECT SE plugin in Docker

CONNECT SE needs to be installed within the container in order to use it. To see how to do that please check Installing plugins in the MariaDB Docker Library Container.

Create JSON data on remote server

The most important feature of CONNECT SE to MariaDB is the flexibility to create tables from various data sources, like the same database and other DMBS’s tables or files with different formats.

MariaDB plugins are software components that may be added to the core software without the need to rebuild the MariaDB Server. Plugins can be storage engines, additional security requirements, special log information about the server and others. MariaDB has a large number of built-in plugins which are permanently installed (listed in SHOW PLUGINS query). Plugins can be loaded at start-up, during initialization, or loaded dynamically when the server is running.

In this blog we are going to see how to list available plugins in the MariaDB container as well as the methods of installing plugins in a container.
