The Confluent Schema Registry is your safeguard against incompatible schema changes and will be the component that ensures no breaking schema evolution will be possible. Kafka Brokers do not look at your payload and your payload schema, and therefore will not reject data

Partitions for newly created topics are assigned in a rack alternating manner, this is the only change broker.rack does

1 is not possible as it doesn't provide resilience to failure, 2 is not enough as if we take a broker down for maintenance, we cannot tolerate a broker failure, and 6 is impossible as we only have 3 brokers (RF cannot be greater than the number of brokers). Here the correct answer is 3

here, we have three tables, but the max.tasks is 2, so that's the maximum number of tasks that will be created

Multiple topics can be passed as a list or regex pattern.
