What is the primary purpose of increasing max.poll.records in a Kafka consumer configuration?

ATo decrease the consumer's memory usage

BTo increase the number of records fetched in one poll, improving throughput

CTo reduce the number of partitions assigned to the consumer

DTo increase the consumer's connection timeout

Step-by-Step Solution

Solution:

Step 1: Understand max.poll.records role
This setting controls how many records the consumer fetches in a single poll call.
Step 2: Effect on throughput
Increasing this value allows the consumer to process more records per poll, which can improve throughput by reducing overhead.
Final Answer:
To increase the number of records fetched in one poll, improving throughput -> Option B
Quick Check:
max.poll.records controls batch size [OK]

Quick Trick: More records per poll means higher throughput [OK]
