apache nifi is a powerful data integration tool that allows you to automate the flow of data between systems. one of its capabilities is to execute python scripts using the `executescript` processor. below is a step-by-step tutorial on how to set this up, along with a code example.
step 1: install dependencies
before using python with nifi, ensure that you have the following:
apache nifi installed and running.
python installed on your machine.
step 2: prepare your python script
create a python script that you want to execute in nifi. for this tutorial, let's create a simple script named `example_script.py` that takes input from nifi, processes it, and outputs the result.
```python
example_script.py
import sys
import json
def process_data(input_data):
here we simply convert the input data to uppercase
return input_data.upper()
read input from standard input (stdin)
if _name_ == "__main__":
input_data = sys.stdin.read().strip()
processed_data = process_data(input_data)
print the processed output (this will be captured by nifi)
print(json.dumps({"result": processed_data}))
```
step 3: add the executescript processor in nifi
1. **open nifi ui**: access the nifi user interface by navigating to `http://localhost:8080/nifi` (or the appropriate url for your installation).
2. **drag and drop the executescript processor**:
from the nifi components toolbar, drag the `executescript` processor onto the canvas.
3. **configure the processor**:
double-click on the `executescript` processor to open its configuration dialog.
set the following properties:
**script engine**: python (make sure the nifi instance has python support).
**script file**: path to your python script, e.g., `/path/to/example_script.py`.
**module directory**: (optional) specify if you have additional python modules.
4. **set input and output**:
in the `settings` tab, configure the relationships. you might want to add ...
