CDC - MySQL Setup Documentation

Prerequisites

To setup CDC between your MySQL database and Peaka BI Table, you need:

MySQL version 5.7, 8.0.x

Setup Instructions

Setting up permissions

In your MySQL primary database, create a database user that must have appropriate permissions on all databases for which the Peaka CDC captures changes.

Create the MySQL user:

CREATE USER <username>@'%' IDENTIFIED WITH mysql_native_password BY 'password';

Grant the required permissions to the user:

GRANT SELECT, RELOAD, SHOW DATABASES, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO <username>@'%';

Finalize the user’s permissions:

FLUSH PRIVILEGES;

Enabling the binlog

Check whether the log-bin option is already on:

// for MySql 5.x
mysql> SELECT variable_value as "BINARY LOGGING STATUS (log-bin) ::"
FROM information_schema.global_variables WHERE variable_name='log_bin';
// for MySql 8.x
mysql> SELECT variable_value as "BINARY LOGGING STATUS (log-bin) ::"
FROM performance_schema.global_variables WHERE variable_name='log_bin';

If it is OFF, configure your MySQL server configuration file with the following properties, which are described in the table below:

server-id         = 223344 # Querying variable is called server_id,
e.g. SELECT variable_value FROM information_schema.global_variables
WHERE variable_name='server_id';
log_bin           = mysql-bin
binlog_format     = ROW
binlog_row_image  = FULL
expire_logs_days  = 10
