Folks,
We're planning on exploring Kafka for our latest work - we are
currently on RabbitMQ. Apologies if this has been already answered.
Question # 1) RMQ offers the Message ordering guarantee, from my initial
read about Kafka - it does seem like a Topic is divided in to Partitions
and any data published to this queue - is distributed among these
partitions based on a certain algorithm.
if there are multiple consumers ( Consumer Group ) consuming from these
partitions how can we ensure that the messages are read in the correct
sequence ? like the RMQ way.
Question # 2) RMQ has semantics of transactions - what is it equivalent in
Kafka.
Question # 3) We use RMQ Federation / Shovelling to communicate across Data
centers in a Hub and Spoke architecture - are there some thing similar in
Kafka.?.
Question # 4) I was reading about Kafka producer - where the crash of the
producer leads to loss of messages - any advice (or) best practice on how
to solve this. ?.
Question # 5) Are there are any open source tools / best practices -
recommended for Kafka performance monitoring tools in case of production
issues.
Question # 6) Kafka consumer is more of a Pull Model - this can cause busy
wait for us - any better ways to fix this.
Thanks a bunch
