Ordering interview questions

1. A.a per-message counter the receiver checks to detect gaps or reordering in a stream
2. B.a guarantee that all messages are delivered in one global sequence, which limits scalability across nodes
3. C.a value attached to a message that determines which partition it lands in, keeping related records together and in sequence
4. D.the situation where messages arrive in a different sequence than sent, common when parallel consumers retry independently

Answer + AI explanation with Pro

1. A.Partition key
2. B.Total ordering
3. C.Partition-level ordering
4. D.Out-of-order delivery

Answer + AI explanation with Pro

1. A.Total ordering — a per-message counter the receiver checks to detect gaps or reordering in a stream
2. B.Total ordering — a guarantee that all messages are delivered in one global sequence, which limits scalability across nodes
3. C.Total ordering — a value attached to a message that determines which partition it lands in, keeping related records together and in sequence
4. D.Total ordering — the property that sequence is preserved only among messages routed to the same partition, not across the whole topic
