KAFKA-4432: Added support to supply custom message payloads to
perf-producer script.
Current implementation of ProducerPerformance creates static payload. This
is not very useful in testing compression or when you want to test with
production/custom payloads. So, we decided to add support for providing payload
file as an input to producer perf test script.
We made the following changes:
1. Added support to provide a payload file which can have the list of
payloads that you actually want to send.
2. Moved payload generation inside the send loop for cases when payload
file is provided.
Following are the changes to how the producer-performance is evoked:
1. You must provide "--record-size" or "--payload-file" but not both. This
is because, record size cannot be guaranteed when you are using custom events.
e.g. ./kafka-producer-perf-test.sh --topic test_topic --num-records
100000 --producer-props bootstrap.servers=127.0.0.1:9092 acks=0
buffer.memory=33554432 compression.type=gzip batch.size=10240 linger.ms=10
--throughput -1 --payload-file ./test_payloads --payload-delimiter ,
2. Earlier "--record-size" was a required config, now you must provide
exactly one of "--record-size" or "--payload-file". Providing both will result
in an error.
3. Support for an additional parameter "--payload-delimiter" has been added
which defaults to "\n"
