问题描述：

在使用logstash同步mysql数据库中的数据，在使用logstash7.4.1以前的版本，输出的sql日志如下：

[2019-12-09T10:50:01,585][INFO ][logstash.inputs.jdbc     ] (0.009082s) SELECT version()

[2019-12-09T10:50:02,043][INFO ][logstash.inputs.jdbc     ] (0.001604s) SELECT * FROM (select * from t_test where updatetime > '1970-01-01 08:00:00' and updatetime < date_add(NOW(), interval -1 second) order by updatetime asc) AS `t1` LIMIT 1 OFFSET 2

[2019-12-09T10:50:02,060][INFO ][logstash.inputs.jdbc     ] (0.001694s) SELECT * FROM (select * from t_test where updatetime > '1970-01-01 08:00:00' and updatetime < date_add(NOW(), interval -1 second) order by updatetime asc) AS `t1` LIMIT 1 OFFSET 3

[2019-12-09T10:50:02,076][INFO ][logstash.inputs.jdbc     ] (0.001766s) SELECT * FROM (select * from t_test where updatetime > '1970-01-01 08:00:00' and updatetime < date_add(NOW(), interval -1 second) order by updatetime asc) AS `t1` LIMIT 1 OFFSET 4

使用logstash7.4.1以后的版本，输出的sql日志如下：

[2019-12-09T15:42:01,445][INFO ][logstash.inputs.jdbc     ][main] (0.009087s) select * from t_test where  updatetime < date_add(NOW(), interval -1 second) order by updatetime asc

logstash input 脚步如下：

jdbc {

jdbc_driver_library => "mysql-connector-java-5.1.47.jar"

jdbc_driver_class => "com.mysql.jdbc.Driver"

jdbc_connection_string => "jdbc:mysql://127.0.0.1:3306/test"

jdbc_user => "root"

jdbc_password => "test"

jdbc_default_timezone =>"Asia/Shanghai"

jdbc_paging_enabled => true

jdbc_page_size => 1

schedule => "* * * * *"

record_last_run => true

use_column_value => true

tracking_column => "updatetime"

tracking_column_type => "timestamp"

last_run_metadata_path => "/Users/future/work/logstash-7.4.2/lastrunmetadata/test"

statement => "select * from t_test where  updatetime < date_add(NOW(), interval -1 second) order by updatetime asc"

}

请问为什么在7.4.1及以后的版本在输出的sql日志中没有LIMIT 1 OFFSET 0分页的相关信息？
