MaxScale 21.06 Maxscale CDC Connector
The C++ connector for the MariaDB MaxScaleCDC system.
Usage
The CDC connector is a single-file connector which allows it to be relatively easily embedded into existing applications.
To start using the connector, either download it from theMariaDB website orconfigure the MaxScale repository
and install the maxscale-cdc-connector
package.
API Overview
A CDC connection object is prepared by instantiating the CDC::Connection
class. To create the actual connection, call the CDC::Connection::connect
method of the class.
After the connection has been created, call the CDC::Connection::read
method
to get a row of data. The CDC::Row::length
method tells how many values a row
has and CDC::Row::value
is used to access that value. The field name of a
value can be extracted with the CDC::Row::key
method and the current GTID of a
row of data is retrieved with the CDC::Row::gtid
method.
To close the connection, destroy the instantiated object.
Examples
The source codecontains an example that demonstrates basic usage of the MaxScale CDC Connector.
Dependencies
The CDC connector depends on:
OpenSSL
RHEL/CentOS 7
Debian Stretch and Ubuntu Xenial
Debian Jessie
openSUSE Leap 42.3
Building and Packaging
To build and package the connector as a library, follow MaxScale build
instructions with the exception of adding -DTARGET_COMPONENT=devel
to the
CMake call.
