我正在使用多个logstash jdbc输入：
jdbc {
jdbc_driver_library => "../vendor/oracle/ojdbc7.jar"
jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
connection_retry_attempts => 10
connection_retry_attempts_wait_time => 5
jdbc_validate_connection => "true"
jdbc_connection_string => "connectionString/myDataBase"
jdbc_user => "USER_NAME"
jdbc_password => "PASSWORD"
schedule => "* * * * *"
statement_filepath => "myPath/queryA.sql"
tracking_column => "myTrackingcolumn"
last_run_metadata_path => "myPath/.logstash_jdbc_last_run"
type => "documentType"
add_field => {
"tag" => "myFirstTag"
}
}
jdbc {

jdbc_validate_connection => "true"
jdbc_connection_string => "connectionString/myDataBase"
jdbc_user => "USER_NAME"

}
}

由于为数据库定义了SESSIONS_PER_USER limit我正在查询，这会引发以下错误：

如何配置这些输入，以便logstash按顺序执行SQL查询并避免超出允许的会话限制？
