Producer

kafka-stress --bootstrap-servers localhost:29092 --events 30000 --topic kafka-stress

kafka-stress --bootstrap-servers localhost:29092 --events 10000 --topic kafka-stress

Customize ACK's

Use --ack parameter to customize ack's quorum

kafka-stress --bootstrap-servers 0.0.0.0:9092 --events 20000 --topic tunning-3 --test-mode producer --ack 1

Producer Format

You can produce random data in string and json format using --format flag

kafka-stress --bootstrap-servers 0.0.0.0:9092 --events 20000 --topic tunning-3 --test-mode producer --ack 1 --format json

Producer Balance Algorithms

You can specify some algorithms to balance producer messages like hash, murmur2 and crc21 using --balance flag

kafka-stress --bootstrap-servers 0.0.0.0:9092 --events 20000 --topic tunning-3 --test-mode producer --balance murmur2 --format json

Consumer

kafka-stress --bootstrap-servers 0.0.0.0:9092 --topic kafka-stress --test-mode consumer --consumers 6

```bash
kafka-stress --bootstrap-servers 0.0.0.0:9092 --events 10000 --topic kafka-stress --test-mode consumer  --consumers 6

...
[Consumer 6] Message from consumer group kafka-stress at topic/partition/offset kafka-stress/1/0: 65b27cc0-1053-4fbc-b7a9-a40972fcaca6 = a124e95d-9226-4eb9-9169-411318bb6e4e

Customize consumer-group name

Use --consumer-group to change customer group name used by workers.

kafka-stress --bootstrap-servers 0.0.0.0:9092 --topic kafka-stress --test-mode consumer --consumer-group custom-consumer-group

Verbose mode

Use --verbose to print keys and events

kafka-stress --bootstrap-servers 0.0.0.0:9092 --topic kafka-stress --test-mode consumer --verbose

Authentication methods

SSL

Use --ssl-enabled to enable ssl authentication.

kafka-stress --bootstrap-servers 0.0.0.0:9092 --topic kafka-stress --test-mode consumer --ssl-enabled
