Kafka - Consumer Groups

AUse a single consumer for all partitions to maintain order.

BUse multiple consumers in a group with multiple partitions; each partition preserves order.

CUse multiple consumer groups consuming the same topic.

DIncrease the number of partitions to one per message.

Step-by-Step Solution

Solution:

Step 1: Understand order guarantees
Kafka guarantees order only within a partition, not across partitions.
Step 2: Use multiple consumers with multiple partitions
Multiple consumers in a group can process partitions in parallel, each preserving order within its partition.
Final Answer:
Use multiple consumers in a group with multiple partitions; each partition preserves order. -> Option B
Quick Check:
Parallel processing with per-partition order = A [OK]

Quick Trick: Order is per partition; parallelism via multiple consumers [OK]
