Hello All, Can someone please help me out how can I write custom filter in logstash to achieve the following: Making a custom logstash filter that sends a query to related indices by wild card (indexname-\*) for records with that(Unique id present in all rollover index) `_id` and if there are existing ones and not belongs to current day's index, it will remove them and insert the current event to **current rollover index** instead. I want to do update/delete operation on my indices data. I would also like to understand will it slowdown logstash events processing to logstash if above is applied?, Surely it will slow down I suppose. Many Thanx ---
