Subject Re: How deep can Drill drill?
Date Thu, 24 Sep 2015 22:39:28 GMT
I am not sure about the impact that nesting would cause, but if you have a
lot of fields (nested or not) in one record, then drill might have some
trouble in allocating memory for each field. If I just want to test how
deep drill can dig, I will create a json document which has a single field
at depth "n". Increase "n" until it breaks.
