GlobalKTable is an abstraction of the changelog stream from which partitions?

• A. All partitions of a topic.
• B. A subset of partitions.
• C. A single partition.
• D. None of the partitions; it's a separate stream.

Answer: (A)

GlobalKTable is built from the changelog streams of all partitions of the source topic, giving every instance a complete copy of the topic’s state. This full, replicated view enables fast local lookups and joins without needing to repartition data. It isn’t limited to a subset or a single partition, nor is it an entirely separate stream; it reflects every partition’s changes.
