This processor takes in a record set and counts both the overall count and counts that are defined as dynamic properties that map a property name to a record path. Record path counts are provided at two levels:

• The overall count of all records that successfully evaluated a record path.
• A breakdown of counts of unique values that matched the record path operation.

Consider the following record structure:

        {
            "sport": "Soccer",
            "name": "John Smith"
        }
    

A valid mapping here would be sport => /sport.

For a record set with JSON like that, five entries and 3 instances of soccer and two instances of football, it would set the following attributes:

• record_count: 5
• sport: 5
• sport.Soccer: 3
• sport.Football: 2
