| <p>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:</p> |
| <ul> |
| <li>The overall count of all records that successfully evaluated a record path.</li> |
| <li>A breakdown of counts of unique values that matched the record path operation.</li> |
| </ul> |
| <p>Consider the following record structure:</p> |
| <pre> |
| { |
| "sport": "Soccer", |
| "name": "John Smith" |
| } |
| </pre> |
| <p>A valid mapping here would be <em>sport => /sport</em>.</p> |
| <p>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:</p> |
| <ul> |
| <li>record_count: 5</li> |
| <li>sport: 5</li> |
| <li>sport.Soccer: 3</li> |
| <li>sport.Football: 2</li> |
| </ul> |
