我在docker容器中运行logstash。那么我如何存储：sql_last_value，以便即使创建了一个新容器，查询也应该使用最后一次使用的值，而不是从一开始就使用？
下面是conf文件。

input {
  jdbc {
    jdbc_driver_library => "<driverpath>/mysql-connector-java-<versionNumber>.jar" 
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://<MySQL host>:3306/es_db" 
    jdbc_user => "<myusername>" 
    jdbc_password => "<mypassword>" 
    jdbc_paging_enabled => true
    tracking_column => "unix_ts_in_secs"
    use_column_value => true
    tracking_column_type => "numeric"
    schedule => "*/5 * * * * *"
    statement => "SELECT *, UNIX_TIMESTAMP(modification_time) AS unix_ts_in_secs FROM es_table WHERE (UNIX_TIMESTAMP(modification_time) > :sql_last_value AND modification_time < NOW()) ORDER BY modification_time ASC"
  }
}
filter {
  mutate {
    copy => { "id" => "[@metadata][_id]"}
    remove_field => ["id", "@version", "unix_ts_in_secs"]
  }
}
output {
  elasticsearch {
    index => "demo_idx"
    document_id => "%{[@metadata][_id]}"
    ilm_enabled => false
    cloud_id => "<cloud_id>"
    cloud_auth => "<cloud_auth>"
    ssl => true
  }
}
