hard📝 Application Q15 of 15

Kafka - Kubernetes and Cloud Deployment

ASet the topic's retention.ms to 604800000 (7 days in milliseconds).

BSet the topic's cleanup.policy to 'compact'.

CSet the topic's max.message.bytes to 7.

DSet the topic's partitions to 7.

Step-by-Step Solution

Solution:

Step 1: Understand retention.ms setting
retention.ms controls how long messages are kept before deletion, in milliseconds.
Step 2: Calculate 7 days in milliseconds
7 days x 24 hours x 60 minutes x 60 seconds x 1000 = 604800000 ms.
Step 3: Match configuration to requirement
Setting retention.ms to 604800000 ensures messages delete after 7 days; other options do not control retention time.
Final Answer:
Set the topic's retention.ms to 604800000 (7 days in milliseconds). -> Option A
Quick Check:
retention.ms = 7 days in ms [OK]

Quick Trick: Use retention.ms for message lifetime in ms [OK]

Common Mistakes:

Confusing cleanup.policy with retention time
Setting max.message.bytes instead of retention
Changing partitions unrelated to retention
