I have a log file as in [this link](https://pastebin.com/jFcCLJr0) which is a composite log format that consists of key value pairs with '=' as the delimiter and csv type of rows with headers which are tab seperated. Still lost on how to parse these logs in logstash.
**Note: The top part of key value pairs should act as metadata for each row.**

This [thread](https://discuss.elastic.co/t/how-to-handle-metadata-in-file-headers/167544) has an example of doing that. Note that it requires "--pipeline.workers 1", so it does not scale, and using class variables can be fragile, but it does the job.
