Hi,  
using logstash I could read data from Mysql.

-I am just asking if logstash reads the new data automaticly from data base?  
-is there a way to memorize the state of the data base to prevent logstash from loading old data. (like sincedb)?

Thank you!

Yes, the jdbc input supports fetching just new/updated rows from the database. See the State section and the example in [the documentation](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-jdbc.html).
