SplitJson processor accept as an input Json array of objects.
How to split json array into individual records using SplitJson processor?
Where can I check examples of "JsonPath Expression" for "SplitJson processor"
I checked documentation for "SplitJson"- but it not covers JsonPath Expressions.
If it is a flat structure you probably want : $.*
Or, if it is some part of a nested structure: $.firstpart.secondpart.*
