easy📝 Syntax Q3 of 15
Kafka - Consumer Groups
Which configuration property specifies the group coordinator in Kafka consumer settings?
Agroup.coordinator
Bgroup.id
Cbootstrap.servers
Dclient.id
Step-by-Step Solution
Solution:

  1. Step 1: Identify the property related to consumer groups

    The group.id property defines the consumer group the client belongs to, which the coordinator uses. bootstrap.servers sets Kafka brokers, client.id identifies the client, and group.coordinator is not a valid config.

  2. Final Answer:

    group.id -> Option B

  3. Quick Check:

    Group coordinator config = group.id [OK]
Quick Trick: Use group.id to join a consumer group, not group.coordinator [OK]
Common Mistakes:
  • Using bootstrap.servers as group coordinator
  • Assuming group.coordinator is a valid config
  • Confusing client.id with group.id
