this is my config file:  
`  
input {  
jdbc {  
jdbc\_driver\_library =\> "/tmp/logstash/logstash-7.9.3/mysql/mysql-connector-java-8.0.16.jar"  
jdbc\_driver\_class =\> "com.mysql.cj.jdbc.Driver"  
jdbc\_page\_size =\> 3  
tracking\_column =\> "id"  
use\_column\_value =\> true

# record\_last\_run =\> true

```
jdbc_connection_string => "jdbc:mysql://192.168.50.254:33066/kuzi?serverTimezone=Asia/Shanghai&useCursorFetch=true"
    jdbc_fetch_size => 5
jdbc_user => cc
jdbc_password => cccc
jdbc_paging_enabled => true
tracking_column_type => "numeric"

```

# schedule =\> "0 0 0 1/1 \* ?"

```
statement => "SELECT * from qq_copy1 where id > :sql_last_value "

```

}  
}

output {

# stdout { codec =\> "rubydebug"}

elasticsearch {  
index =\> "qqq"  
hosts =\> ["127.0.0.1:9200"]  
document\_id =\> "%{id}"  
}  
}  
`  
I hope query order is  
select \* from (select \* from qq\_qqcopy1 where id \> 0) limit 3 offset 0  
select \* from (select \* from qq\_qqcopy1 where id \> 3) limit 3 offset 0  
select \* from (select \* from qq\_qqcopy1 where id \> 6) limit 3 offset 0  
use this query mode.

i have mass data, if statement is 'SELECT \* from qq\_copy1', query speed very slow. so help please
