Study Notes
Kafka Topics
- Kafka Topics are the core unit of data organization in Kafka.
- Topics are used to store streams of records, enabling a persistent and scalable way to exchange data.
- Kafka-topics is a console script that facilitates the creation and management of Kafka Topics.
- To create a topic, the following command is used:
kafka-topics --bootstrap-server localhost:9092 --create --topic users --partitions 4 --replication-factor 1 - The
--bootstrap-serverflag specifies the host and port of the Kafka broker. - The
--topicflag defines the name of the topic to create. - The
--partitionsflag sets the number of partitions for the topic. - The
--replication-factorflag determines the number of copies of each partition for fault tolerance. - The
kafka-topicscommand also supports other functionalities, such as listing, describing, and deleting topics. - The
--describeflag provides information about a specific topic, including its configuration, partitions, and replicas. - The
kafka-console-producerscript is used to produce data to a Kafka topic. kafka-console-producer --bootstrap-server localhost:9092 --property key.separator=, --property parse.key=true --topic usersis the command to produce data.- The
--property key.separator=flag defines the separator between key and value. - The
--property parse.key=trueflag enables the parsing of the key. - The
--topicflag specifies the target topic for data production.
