Lets say I have a string:
"petBreed":"dachshund" "petName":"rufus" "petAge":"12"
The value is not constant and can vary in length and content.
And i want to use grok overwrite to remove rufus from the raw string.
So a lookbehind and lookahead regex pattern that matches based on a match to petName, then removes the string after it thru grok overwrite
