fun main() {
    val database = LiquibaseDatabaseFactory.create(
        driver = "com.mysql.cj.jdbc.Driver",
        url = "jdbc:mysql://localhost:3306/test_db",
        username = "root",
        password = "",

    val client = momosetkn.liquibase.client.LiquibaseClient(
        changeLogFile = /* your changeLog file path here */,
        database = database,
    ).also {
        // SlowLogChangeLog
        it.changeExecListener = SlowLogChangeExecListener()
        // or Setting option
        it.changeExecListener = SlowLogChangeExecListener(
            threshold = 1.seconds, // optional
