you need specify schedule in jdbc input:

the schedule below (* * * * *) run every minute , select records database , select records have been updated after last time query ran. updated timestamp field might named differently, feel free adjust fit case. 

input {   jdbc {     jdbc_driver_library => "mysql-connector-java-5.1.36-bin.jar"     jdbc_driver_class => "com.mysql.jdbc.driver"     jdbc_connection_string => "jdbc:mysql://localhost:3306/mydb"     jdbc_user => "mysql"     parameters => { "some_field" => "value" }     schedule => "* * * * *"     statement => "select * songs some_field = :some_field , updated > :sql_last_value"   } }
