Kafka - Performance Tuning

ADelete the topic and create a new one with 1 partition

BDecrease the partition count to 3 to reduce complexity

CKeep partition count at 5 and add more consumers than partitions

DIncrease the partition count to 10 and rebalance consumers

Step-by-Step Solution

Solution:

Step 1: Understand effect of partition count on parallelism
More partitions allow more consumers to read in parallel, increasing throughput.
Step 2: Evaluate options for increasing parallel processing
Increasing partitions to 10 allows better parallelism; rebalance consumers to use new partitions.
Final Answer:
Increase the partition count to 10 and rebalance consumers -> Option D
Quick Check:
More partitions = better parallel processing [OK]

Quick Trick: More partitions mean more parallel consumers [OK]
