Configuration

MySQL Configuration

Ensure that the MySQL authentication info in src/main/resources/application.conf is correct. You can override the defaults during development by creating a src/main/resources/application.overrides.conf file, which is git ignored:

changestream {
  mysql {
    host = "localhost"
    port = 3306
    user = "changestream"
    password = "changestreampass"
  }
}

You can also configure most settings using environment variables. For example, you could put the following in a Changestream init script:

export MYSQL_HOST=localhost
export MYSQL_PORT=3306
export MYSQL_USER=changestream
export MYSQL_PASS=changestreampass

Emitter Configuration

If you would like to override the default emitter (StdoutActor), you can do so by setting changestream.emitter or the EMITTER environment variable to the fully qualified class name (for example, changestream.actors.SnsActor).

To configure the SNS emitter, you must provide AWS credentials, and configure changestream.aws.sns.topic.
