I just discovered slf4j's fluent API yesterday, and tried to use it.
Unfortunately the key/value pairs I added with addKeyValue() in slf4j 2.0.7/logstash 7.3.0 were lost from the output.
I had hoped for at least the default slf4j behaviour, which is putting them into "{} " entries at the start of the formatted messages.
Does newer versions than logstash 7.3.0 support addKeyValue() from the slf4j fluent API?
Thanks!
