I want to remove a field starting with ElapsedTimeAt\* in my remove processor pipeline. Is it possible? ---

Reading the code, I don't think it is possible to use wildcards. > ---

Thanks for the quick reply. This is what i am trying to achieve. I have a incoming document and in Logstash i add a field for which the name is dynamic (filed name will be ElapsedTimeAt\_timestamp where timestamp will be substituted with @timestamp value). This field i need to make it available in one index and should be removed before indexing into other index. Struggling to implement this. Is there any way to do this ?? ---

Can i have something like ctx.ElapsedTimeAt\_%{timestamp} ? Will it compute the column name dynamically ? If you have any example that would help me great .. ---

Yes you can have something similar to this if there is a field which contains the value you are looking for. See [https://www.elastic.co/guide/en/elasticsearch/reference/6.6/accessing-data-in-pipelines.html#accessing-template-fields](https://www.elastic.co/guide/en/elasticsearch/reference/6.6/accessing-data-in-pipelines.html#accessing-template-fields) For Ingest Script Processor, read [https://www.elastic.co/guide/en/elasticsearch/reference/6.6/script-processor.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.6/script-processor.html). I'm not a painless expert so I can't really tell how to read all the fields from your documents and compare to a regex/wildcard and remove it or not. ---
