Please have a look into the ruby filter documentation and assess if it is possible for you to load your csv in the init => "" config of the filter to load it only once.

And did you have a look in the translate filter https://www.elastic.co/guide/en/logstash/current/plugins-filters-translate.html that might suits your usecase
