Example use case: You are confirming record arrivals and you'd like to read from a specific offset in a topic partition. We can see this consumer has read messages from the topic and printed it on a console. We can use KafkaConsumer.seek function to seek a specific offset and start to read from there.. We have created our first Kafka consumer in python. In this case your application will create a consumer object, subscribe to the appropriate topic, and start receiving messages, validating them and writing the results. Default: ‘kafka-python-{version}’ group_id (str or None) – name of the consumer group to join for dynamic partition assignment (if enabled), and to use for fetching and committing offsets. With this write-up, I would like to share some of the reusable code snippets for Kafka Consumer API using Python library confluent_kafka. Below is my code. In this tutorial you'll learn how to use the Kafka console consumer to quickly debug issues by reading from a specific offset as well as control the number of records you read. Python Tkinter. Now, to find the last offset of the topic, i.e. Suppose you have an application that needs to read messages from a Kafka topic, run some validations against them, and write the results to another data store. def read_message(topic ,partition, broker, from_offset, until_offset): clientName … Kafka consumer offset latest Kafka consumer offset latest.

If None, auto-partition assignment (via group coordinator) and offset commits are disabled. To avoid setting a new group.id each time you want to read a topic from its beginning, you can disable auto commit (via enable.auto.commit = false) before starting the consumer for the very first time (using an unused group.id and setting auto.offset.reset = earliest). Read messages from a specified offset. Now, this offset is the last offset that is read by the consumer from the topic.
