resource "google_sql_database_instance" "read_replica" {
  name                 = "mysql-replica-instance-name"
  master_instance_name = google_sql_database_instance.primary.name
  region               = "europe-west4"
  database_version     = "MYSQL_8_0"

  replica_configuration {
    failover_target = false
  }

  settings {
    tier              = "db-n1-standard-2"
    availability_type = "ZONAL"
    disk_size         = "100"
  }
  # set `deletion_protection` to true, will ensure that one cannot accidentally delete this instance by
  # use of Terraform whereas `deletion_protection_enabled` flag protects this instance at the GCP level.
  deletion_protection = false
}
