I just have a conceptual question about how logstash import same files.
Let's say I have done with the previous data ingesting. I terminated the process of logstash after that.And I do not change the data source file or corresponding config file. They are exactly same as before. If I restart the logstash with the same config setting, would the data be replaced by the new one(even if they are same) or logstash automatically recognizes they are same so it will not import any new data?
