Hi All, I have to populate a field in index with its full form from its short form. For this I have to use hashmap or any property holder to convert the field value from its short form to long form(full form). If a field with state code coming as TX. I have to change it to Texas in new index. How to do that? ---

The Translate plugin [https://www.elastic.co/guide/en/logstash/current/plugins-filters-translate.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-translate.html) sounds like it probably does what you want 🙂 ---
