Description
This adds a new ottl function called
Keys
The idea here is because, I have a use case to debug traces being sent to newrelic where some spans are being dropped because of the attribute's names (and they don't specify which). The final idea is to be able to filter out attributes that are bigger than the threshold specified by them and send to a log or something.
A next step would be some sort of filter function like
Filter(Keys(resource.attributes), Len(key) > 100)
An ugly implementation of the fiter can be seen here main...jaysonsantos:opentelemetry-collector-contrib:ottl-add-filter-function
