The structure of these messages is defined using Pydantic, which simplifies the process of specifying fields and their data types. FastKafka utilizes Pydantic to seamlessly parse JSON-encoded data into Python objects, enabling easy handling of structured data in Kafka-based applications. + +Example: Here's an example of a message for a simple use case: + +```python +from typing import * +from pydantic import BaseModel, Field, NonNegativeFloat + + +class StoreProduct(BaseModel): + product_name: str = Field(..., description="Name of the product") + currency: str = Field(..., description="Currency") + price: NonNegativeFloat = Field(..., description="Price of the product") +``` + +In the provided example, the "StoreProduct" message class is inherited from Pydantic's BaseModel class and includes three fields: "product_name," "currency," and "price." Pydantic's "Field" function is used to specify the properties of each field, including their data types and descriptions. + +Application: + +We can create a new application object by initialising the FastKafka class with the minimum set of arguments.

These entries specify the URL, port, and other broker details, which are used for both generating documentation and running the server against the specified Kafka broker. + +Function decorators in FastKafka: + +FastKafka provides two convenient decorator functions: @kafka_app.consumes and @kafka_app.produces. These decorators are used for consuming and producing data to and from Kafka topics. They also handle the decoding and encoding of JSON-encoded messages. + +@kafka_app.consumes decorator function: + +You can use the @kafka_app.consumes decorator to consume messages from Kafka topics. + +Example: Consuming messages from a "hello_world" topic + +```python +from typing import * +from pydantic import BaseModel + +class HelloWorld(BaseModel): + name: str = Field( + ..., description="Name to send in a Kafka topic" + ) + +@kafka_app.consumes(topic="hello_world") +async def on_hello_world(msg: HelloWorld): + print(f"Got msg: {msg.name}") +``` +In the provided example, the @kafka_app.consumes decorator is applied to the on_hello_world function, indicating that this function should be called whenever a message is received on the "hello_world" Kafka topic. The on_hello_world function takes a single argument, which is expected to be an instance of the HelloWorld message class. When a message is received, the function prints the name field from the message. + +@kafka_app.consumes decorator function: + +You can use @kafka_app.produces decorator to produce messages to Kafka topics. + +Example: Producing messages to a "hello_world" topic + +```python +from typing import * +from pydantic import BaseModel + +class HelloWorld(BaseModel): + name: str = Field( + ..., description="Name to send in a kafka topic" + ) + +@kafka_app.produces(topic="hello_world") +async def to_hello_world(name: str) -> HelloWorld: + return HelloWorld(name=name) +``` + +In this example, the @kafka_app.produces decorator is applied to the to_hello_world function. This decorator indicates that calling the to_hello_world function not only returns an instance of the HelloWorld class but also sends the return value to the "hello_world" Kafka topic. + +Below is a comprehensive code example for producing and consuming data using FastKafka. We will create a basic FastKafka application that consumes data from the "input_data" topic, logs the data using a logger, and then produces the incremented data to the "output_data" topic. + +```python +from pydantic import BaseModel, Field, NonNegativeFloat + +from fastkafka import FastKafka +from fastkafka._components.logger import get_logger + +logger = get_logger(__name__) + +class Data(BaseModel): + data: NonNegativeFloat = Field( + ..., example=0.5, description="Float data example" + ) + +kafka_brokers = { + "localhost": { + "url": "localhost", + "description": "local development kafka broker", + "port": 9092, + }, + "production": { + "url": "kafka.airt.ai", + "description": "production kafka broker", + "port": 9092, + "protocol": "kafka-secure", + "security": {"type": "plain"}, + }, +} + +kafka_app = FastKafka( + title="Demo Kafka app", + kafka_brokers=kafka_brokers, +) + +@kafka_app.consumes(topic="input_data", auto_offset_reset="latest") +async def on_input_data(msg: Data): + logger.info(f"Got data: {msg.data}") + await to_output_data(msg.data) + + +@kafka_app.produces(topic="output_data") +async def to_output_data(data: float) -> Data: + processed_data = Data(data=data+1.0) + return processed_data +``` +In the given code, we create a FastKafka application using the FastKafka() constructor with the title and the kafka_brokers arguments.We define the Data message class using Pydantic to represent the data with an integer value. The application is configured to consume messages from the "input_data" topic, log the data using a logger named "data_logger," and then produce the incremented data to the "output_data" topic. + +Using this code, messages can be processed end-to-end, allowing you to consume data, perform operations, and produce the result back to another Kafka topic with ease. +''' + +# %% ../../nbs/Code_Generation_Prompts.ipynb 3 +APP_VALIDATION_PROMPT = """ +You should respond with 0, 1 or 2 and nothing else.
