Hi kvch, thank you for the reply.
My pipeline is already up and running nicely: filebeat monitors a folder for all csv files, ships data to logstash where data is parsed and filtered, then sent to ES.
When an entry in a csv file has its value modified, I want the pipeline to reread it and reindex it in ES. I read everything I found on reindexing. The problen is, as far as I found this is a highly manual task done through the dev section in kibana using PUT.
I don't prefer doing it this way, nor deleting entries in the registry. Once a csv entry is modified I need the changes to be reflected in my kibana dashboard. This is critical for my work.
