Hello,  
I am using Logstash 5 with dictionary lookups and a refresh interval of 60 seconds. I am having an issue where if I remove a line from a yml file, the change is not picked up until i restart Logstash. Adding or changing data works fine and updates without a restart. Has anyone else run across this and maybe have a work-around?

Thanks  
Chris

I can't think of a work around.

The existing dictionary is merged with newly read dictionary - so old K/V will stick around.

Maybe change the value of a no-longer-valid key to "\_\_no\_longer\_valid" and add some processing to remove the field if that value is seen?
