Servers in the city Kafka cluster store topic partitions and serve produce and fetch requests. What are those servers called?
Select an answer to reveal the explanation.
Short Explanation
Brokers are the library buildings. They hold the shelves of partitions and hand records to whoever publishes or checks them out.
Full Explanation
Servers in the city Kafka cluster that store topic partitions and serve produce and fetch requests are brokers. Brokers are the storage and network serving tier of the cluster. They are not end-user dashboards, not producers embedded exclusively inside every fare gate, and not temporary spreadsheets that replace the cluster overnight. Exam caveat: broker disk, replication factor, and partition leadership determine durability and availability during maintenance. Operational check: list brokers in the cluster, confirm each holds replicas for assigned partitions, and validate a controlled broker restart does not lose acknowledged taps under the configured replication factor. In production terms for Kafka brokers storing partitions, assign an owning team, wire a dashboard that shows the pattern is healthy under peak civic load, and require a staging drill that rehearses failure and recovery before resident impact. Revisit the choice when traffic shape, retention, or integrity needs change, and keep a named rollback owner on the change record. Re-test both the happy path and the failure path for Kafka brokers storing partitions after material dependency upgrades so regressions are caught before the next public release.
