Installing CONNECT

The CONNECT storage engine enables MariaDB to access external local or remote data (MED). This is done by defining tables based on different data types, in particular files in various formats, data extracted from other DBMS or products (such as Excel or MongoDB) via ODBC or JDBC, or data retrieved from the environment (for example DIR, WMI, and MAC tables)

This storage engine supports table partitioning, MariaDB virtual columns and permits defining special columns such as ROWID, FILEID, and SERVID.

The storage engine must be installed before it can be used.

Installing the Plugin's Package

The CONNECT storage engine's shared library is included in MariaDB packages as the ha_connect.so or ha_connect.so shared library on systems where it can be built.

Installing on Linux

The CONNECT storage engine is included in on Linux.

Installing with a Package Manager

The CONNECT storage engine can also be installed via a package manager on Linux. In order to do so, your system needs to be configured to install from one of the MariaDB repositories.

You can configure your package manager to install it from MariaDB Corporation's MariaDB Package Repository by using the .

You can also configure your package manager to install it from MariaDB Foundation's MariaDB Repository by using the .

Installing with yum/dnf

On RHEL, CentOS, Fedora, and other similar Linux distributions, it is highly recommended to install the relevant from MariaDB's repository using or . Starting with RHEL 8 and Fedora 22, yum has been replaced by dnf, which is the next major version of yum. However, yum commands still work on many systems that use dnf:

Installing with apt-get

On Debian, Ubuntu, and other similar Linux distributions, it is highly recommended to install the relevant from MariaDB's repository using :

Installing with zypper

On SLES, OpenSUSE, and other similar Linux distributions, it is highly recommended to install the relevant from MariaDB's repository using :

Installing the Plugin

Once the shared library is in place, the plugin is not actually installed by MariaDB by default. There are two methods that can be used to install the plugin with MariaDB.

The first method can be used to install the plugin without restarting the server. You can install the plugin dynamically by executing or :

The second method can be used to tell the server to load the plugin when it starts up. The plugin can be installed this way by providing the or the options. This can be specified as a command-line argument to or it can be specified in a relevant server in an :

Uninstalling the Plugin

You can uninstall the plugin dynamically by executing or :

If you installed the plugin by providing the or the options in a relevant server in an , then those options should be removed to prevent the plugin from being loaded the next time the server is restarted.

Installing Dependencies

The CONNECT storage engine has some external dependencies.

Installing unixODBC

The CONNECT storage engine requires an ODBC library. On Unix-like systems, that usually means installing . On some systems, this is installed as the unixODBC package:

On other systems, this is installed as the libodbc1 package:

If you do not have the ODBC library installed, then you may get an error about a missing library when you attempt to install the plugin:
