API

Usage

Send the output of a function to Kafka

from kafkaPythonWrapper import MessageSender

message_sender = MessageSender(topic='test')

@message_sender.send_sync()
def produce_message():
    key, value = 'email_address', '[e-mail]'
    print(f'{key}: {value}')
    yield key, value

Receive and print messages from Kafka

from kafkaPythonWrapper import MessageCollector

message_collector = MessageCollector(topic='test', group_id='1')

@message_collector.consume
def print_message(**kwargs):
    print(kwargs)

Close producer or consumer

message_sender.close()
message_collector.close()
