Generally filebeat mapping creating a lot of unused fields in my elasticsearch environment. I wonder, because size of the logs are excessivelly large (around 5-6 GB per day). Can I somehow delete unused mapping from index? Because if this is DB-like, I don't need table where every record contains around thousand nulls. How can I fit it, or it isn't use additional disk space?
Please correct me if I am wrong, but for comparrison, the same logs from the same source in wazuh weight like 8-10 times less.
Thanks in advance for reply and have a good day
