I used the following translate filter in logstash

translate {  
field =\> "countries"  
destination =\> "cities"  
dictionary\_path =\> "/home/rrr/cities.yml"  
}

And I started logstash this way

/usr/share/logstash/bin/logstash -f $directory --path.settings=/etc/logstash -t

Everything went well and good.

My question is :

Would logstash will take into account any modification that I may do in the dictionary\_path file ?  
I means do I need to restart logstash after any edition on this file or not ?

Yes, see the `refresh_interval` configuration option.
