Hello,
I did a test with these two rb scripts which take the time almost the
same. do you have the further idea?
$ cat async-pub.rb
require 'kafka'
kafka = Kafka.new("localhost:9092", client_id: "ruby-client",
resolve_seed_brokers: true)
producer = kafka.async_producer(required_acks:
Hi frakass,
I think the most difference for sync and async send (or "publish" like you
said), is the throughput.
You said the performance is almost the same, and I would guess the "acks"
config in your environment might be 0? Or maybe the produce rate is slow?
Or
for a producer, is there a principle that when to use sync publishing,
and when to use async publishing?
for the simple format messages, i have tested both, their performance
are almost the same.
Thank you.

Hi,
Recently, in a 3.8.1 Kafka cluster with 3 brokers, the topic __consumer_offsets
became leaderless:
$ /kafka-topics.sh --zookeeper --describe
--under-replicated-partitions
Topic: __consumer_offsets Partition: 0
Leader: none Replicas: 103,101,102
