Given this consumer config snippet:

props.put("max.poll.records", "500");
props.put("fetch.max.bytes", "1048576");
props.put("fetch.min.bytes", "1");

What is the maximum number of records the consumer can receive in one poll?

A1048576

B500

C1

DUnlimited

Step-by-Step Solution

Solution:

Step 1: Identify max.poll.records role
This setting limits the maximum number of records returned in a single poll call.
Step 2: Understand fetch.max.bytes and fetch.min.bytes
fetch.max.bytes limits data size, fetch.min.bytes is minimum data to fetch; neither directly limits record count.
Final Answer:
500 -> Option B
Quick Check:
max.poll.records = max records per poll [OK]

Quick Trick: max.poll.records caps records per poll call [OK]
