Kafka utilities are now available:
Creating a New Topic
kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 3 --topic my-topic
Verify the topic
kafka-topics --list --zookeeper localhost:2181
Adding Partitions
kafka-topics --zookeeper localhost:2181 --alter --topic my-topic --partitions 16
Deleting a Topic
kafka-topics --zookeeper localhost:2181 --delete --topic my-topic
Listing All Topics in a Cluster
kafka-topics --zookeeper localhost:2181 --list
Describing Topic Details
kafka-topics --zookeeper localhost:2181/kafka-cluster --describe
Show Under-replicated Partitions for topics
kafka-topics --zookeeper localhost:2181/kafka-cluster --describe --under-replicated-partitions
Produce messages standard input
kafka-console-producer --broker-list localhost:9092 --topic my-topic
Produce messages file
kafka-console-producer --broker-list localhost:9092 --topic test < messages.txt
Produce Avro messages
kafka-avro-console-producer --broker-list localhost:9092 --topic my.Topic --property value.schema='{"type":"record","name":"myrecord","fields":[{"name":"f1","type":"string"}]}' --property schema.registry.url=http://localhost:8081
And enter a few values from the console:
{"f1": "value1"}
Start a consumer from the beginning of the log
kafka-console-consumer --bootstrap-server localhost:9092 --topic my-topic --from-beginning
Consume messages and display message keys
kafka-console-consumer --bootstrap-server localhost:9092 --topic my-topic --property print.key=true --property key.seperator=, --from-beginning
Consume 1 message
kafka-console-consumer --bootstrap-server localhost:9092 --topic my-topic --max-messages 1
Consume 1 message from __consumer_offsets
kafka-console-consumer --bootstrap-server localhost:9092 --topic __consumer_offsets --formatter 'kafka.coordinator.GroupMetadataManager$OffsetsMessageFormatter' --max-messages 1
Consume, specify consumer group:
kafka-console-consumer --topic my-topic --new-consumer --bootstrap-server localhost:9092 --consumer-property group.id=my-group
kafka-avro-console-consumer --topic position-reports --new-consumer --bootstrap-server localhost:9092 --from-beginning --property schema.registry.url=localhost:8081 --max-messages 10
kafka-avro-console-consumer --topic position-reports --new-consumer --bootstrap-server localhost:9092 --from-beginning --property schema.registry.url=localhost:8081
List Groups
kafka-consumer-groups --new-consumer --list --bootstrap-server localhost:9092
Describe Groups
kafka-consumer-groups --bootstrap-server localhost:9092 --describe --group testgroup
Set the retention for the topic
kafka-configs --zookeeper localhost:2181 --alter --entity-type topics --entity-name my-topic --add-config retention.ms=3600000
Show all configuration overrides for a topic
kafka-configs --zookeeper localhost:2181 --describe --entity-type topics --entity-name my-topic
Delete a configuration override for retention.ms for a topic
kafka-configs --zookeeper localhost:2181 --alter --entity-type topics --entity-name my-topic --delete-config retention.ms
Producer
kafka-producer-perf-test --topic position-reports --throughput 10000 --record-size 300 --num-records 20000 --producer-props bootstrap.servers="localhost:9092"
