| <!-- Processor Documentation ================================================== --> |
| <p> |
| <strong>Note:</strong> The underlying JsonPath library loads the entirety of the streamed content into and performs |
| result evaluations in memory. Accordingly, it is important to consider the anticipated profile of content being |
| evaluated by this processor and the hardware supporting it especially when working against large JSON documents. |
| </p> |
| |
| <h3>Additional Notes</h3> |
| <p> |
| It's a common pattern to make JSON from attributes in NiFi. Many of these attributes have periods in their names. For example |
| <em>record.count</em>. To reference them safely, you must use this sort of operation which puts the entire key in brackets. |
| This also applies to JSON keys that contain whitespace: |
| </p> |
| <blockquote>$.["record.count"]</blockquote> |
| <blockquote>$.["record count"]</blockquote> |
| </body> |
