This page summarizes commonly used Apache Kafka Windows commands.
Prerequisites
Setup an environment variable named KAFKA_HOME that points to where Kafka is located.
Example:
SET KAFKA_HOME=F:\big-data\kafka_2.13-2.6.0
warning Remember to change the server address, port number and Kafka topic name accordingly before running any of the following command.
Start Kafka brokers (incl. ZookKeeper)
%KAFKA_HOME%/bin/windows/zookeeper-server-start.bat %KAFKA_HOME%/config/zookeeper.properties
%KAFKA_HOME%/bin/windows/kafka-server-start.bat %KAFKA_HOME%/config/server.properties
Stop Kafka brokers
%KAFKA_HOME%/bin/windows/kafka-server-stop.bat %KAFKA_HOME%/config/server.properties %KAFKA_HOME%/bin/windows/zookeeper-server-stop.bat %KAFKA_HOME%/config/zookeeper.properties
Kafka topic command
%KAFKA_HOME%/bin/windows/kafka-topics.bat
Command must include exactly one action: --list, --describe, --create, --alter or --delete
Option Description
------ -----------
--alter Alter the number of partitions,
replica assignment, and/or
configuration for the topic.
--at-min-isr-partitions if set when describing topics, only
show partitions whose isr count is
equal to the configured minimum. Not
supported with the --zookeeper
option.
--bootstrap-server <String: server to REQUIRED: The Kafka server to connect
connect to> to. In case of providing this, a
direct Zookeeper connection won't be
required.
--command-config <String: command Property file containing configs to be
config property file> passed to Admin Client. This is used
only with --bootstrap-server option
for describing and altering broker
configs.
--config <String: name=value> A topic configuration override for the
topic being created or altered.The
following is a list of valid
configurations:
cleanup.policy
compression.type
delete.retention.ms
file.delete.delay.ms
flush.messages
flush.ms
follower.replication.throttled.
replicas
index.interval.bytes
leader.replication.throttled.replicas
max.compaction.lag.ms
max.message.bytes
message.downconversion.enable
message.format.version
message.timestamp.difference.max.ms
message.timestamp.type
min.cleanable.dirty.ratio
min.compaction.lag.ms
min.insync.replicas
preallocate
retention.bytes
retention.ms
segment.bytes
segment.index.bytes
segment.jitter.ms
segment.ms
unclean.leader.election.enable
See the Kafka documentation for full
details on the topic configs.It is
supported only in combination with --
create if --bootstrap-server option
is used.
--create Create a new topic.
--delete Delete a topic
--delete-config <String: name> A topic configuration override to be
removed for an existing topic (see
the list of configurations under the
--config option). Not supported with
the --bootstrap-server option.
--describe List details for the given topics.
--disable-rack-aware Disable rack aware replica assignment
--exclude-internal exclude internal topics when running
list or describe command. The
internal topics will be listed by
default
--force Suppress console prompts
--help Print usage information.
--if-exists if set when altering or deleting or
describing topics, the action will
only execute if the topic exists.
--if-not-exists if set when creating topics, the
action will only execute if the
topic does not already exist.
--list List all available topics.
--partitions <Integer: # of partitions> The number of partitions for the topic
being created or altered (WARNING:
If partitions are increased for a
topic that has a key, the partition
logic or ordering of the messages
will be affected). If not supplied
for create, defaults to the cluster
default.
--replica-assignment <String: A list of manual partition-to-broker
broker_id_for_part1_replica1 : assignments for the topic being
broker_id_for_part1_replica2 , created or altered.
broker_id_for_part2_replica1 :
broker_id_for_part2_replica2 , ...>
--replication-factor <Integer: The replication factor for each
replication factor> partition in the topic being
created. If not supplied, defaults
to the cluster default.
--topic <String: topic> The topic to create, alter, describe
or delete. It also accepts a regular
expression, except for --create
option. Put topic name in double
quotes and use the '\' prefix to
escape regular expression symbols; e.
g. "test\.topic".
--topics-with-overrides if set when describing topics, only
show topics that have overridden
configs
--unavailable-partitions if set when describing topics, only
show partitions whose leader is not
available
--under-min-isr-partitions if set when describing topics, only
show partitions whose isr count is
less than the configured minimum.
Not supported with the --zookeeper
option.
--under-replicated-partitions if set when describing topics, only
show under replicated partitions
--version Display Kafka version.
--zookeeper <String: hosts> DEPRECATED, The connection string for
the zookeeper connection in the form
host:port. Multiple hosts can be
given to allow fail-over.List Kafka topics
%KAFKA_HOME%/bin/windows/kafka-topics.bat --list --bootstrap-server localhost:9092
Create Kafka topic
%KAFKA_HOME%/bin/windows/kafka-topics.bat --create --topic kontext-kafka --bootstrap-server localhost:9092
Describe Kafka topic
%KAFKA_HOME%/bin/windows/kafka-topics.bat --describe --topic kontext-kafka --bootstrap-server localhost:9092
Example output:
Topic: kontext-kafka PartitionCount: 3 ReplicationFactor: 1 Configs: segment.bytes=1073741824
Topic: kontext-kafka Partition: 0 Leader: 0 Replicas: 0 Isr: 0
Topic: kontext-kafka Partition: 1 Leader: 0 Replicas: 0 Isr: 0
Topic: kontext-kafka Partition: 2 Leader: 0 Replicas: 0 Isr: 0*In my Kafka environment, there is only one node thus Leader is always 0 and replica is also 0.
Delete Kafka topic
%KAFKA_HOME%/bin/windows/kafka-topics.bat --delete --topic kontext-kafka --bootstrap-server localhost:9092
