I have to parse huge amount of log files in logstash. I stored all log files in one directory with .gz format. when I try to extract those logs the size becomes very high. Let's say the log file size is 50MB when it is in .gz format. but after extract that it will become 1 GB. can I parse these logs in effective way instead of unzip all the log files at a time? or can I extract those log files one by one when once a log files is completely parsed in logstash?
