Hello, I configured Logstash to read one jdbc input (mysql) and put information in elasticsearch, all this run ok. But now I need some parameters of a second input (other mysql database) that must be passed to SQL statement of the first input, that is to say, the first DB have the main data and second DB have a required parameters to filter the SQL statement of first DB.

I have been searching if this is possible but I can not find nothing, ¿How can I do that, some idea?

Thanks.
