In short, Spark Streaming supports Kafka but there are still some rough edges. A good starting point for me has been the KafkaWordCount example in the Spark code base (Update 2015-03-31: see also DirectKafkaWordCount).

Today we would like to share our experience with Apache Spark , and how to deal with one of the most annoying aspects of the framework. This article assumes basic knowledge of Apache Spark. If you feel uncomfortable with the basics of Spark, we recommend you to participate in an excellent online course prepared Se hela listan på data-flair.training Spark code for integration with Kafka from pyspark.sql import SparkSession from pyspark.sql.functions import * from pyspark.sql.types import * import math import string import random KAFKA_INPUT_TOPIC_NAME_CONS = “inputmallstream” KAFKA_OUTPUT_TOPIC_NAME_CONS = “outputmallstream” KAFKA_BOOTSTRAP_SERVERS_CONS = ‘localhost:9092’ MALL_LONGITUDE=78.446841 MALL_LATITUDE=17.427229 MALL In this video, We will learn how to integrated Kafka with Spark along with a Simple Demo.

How can we combine and run Apache Kafka and Spark together to achieve our goals? The KafkaInputDStream of Spark Streaming – aka its Kafka “connector” – uses Kafka’s high-level consumer API, which means you have two control knobs in Spark that determine read parallelism for Kafka: The number of input DStreams. In order to integrate Kafka with Spark we need to use spark-streaming-kafka packages. The below are the version available for this packages. It clearly shows that in spark-streaming-kafka-0–10 Spark Streaming – Kafka Integration Strategies At this point, it is worthwhile to talk briefly about the integration strategies for Spark and Kafka.
spark-kafka. Spark-kafka is a library that facilitates batch loading data from Kafka into Spark, and from Spark into Kafka. This library does not provide a Kafka Input DStream for Spark Streaming. For that please take a look at the spark-streaming-kafka library that is part of Spark itself.

Spark periodically queries Kafka to get the latest offsets in each topic and partition that it is interested in consuming from. At the beginning of every batch interval, the range of offsets to consume is decided. Spark then runs jobs to read the Kafka data that corresponds to the offset ranges determined in the prior step. In this article we will discuss about the integration of spark (2.4.x) with kafka for batch processing of queries. Kafka:-.
