💡 Hint

Common Mistakes

Using a string instead of a numeric value.

Setting too small a buffer size causing frequent blocking.

The buffer.memory property expects a numeric value representing the total bytes of memory the producer can use to buffer records.

2fill in blank

medium

Complete the code to configure the batch size for Kafka producer buffers.

Kafka

props.put("batch.size", [1]);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using a string instead of an integer.

Setting batch size too large causing latency.

The batch.size property sets the maximum number of bytes to batch before sending to the broker.

3fill in blank

hard

Fix the error in setting linger.ms to control buffer delay.

Kafka

props.put("linger.ms", [1]);

Drag options to blanks, or click blank then click option'

A"100"

Ctrue

D"true"

💡 Hint

Common Mistakes

Passing linger.ms as a string instead of an integer.

Using boolean values which are invalid.

The linger.ms property expects an integer value representing milliseconds to wait before sending a batch.

4fill in blank

hard

Fill both blanks to configure buffer memory and batch size correctly.

Kafka

props.put("buffer.memory", [1]);
props.put("batch.size", [2]);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using strings instead of integers.

Mixing up the values for buffer.memory and batch.size.

Buffer memory and batch size must be set as numeric values representing bytes.

5fill in blank

hard

Fill all three blanks to configure buffer.memory, batch.size, and linger.ms properly.

Kafka

props.put("buffer.memory", [1]);
props.put("batch.size", [2]);
props.put("linger.ms", [3]);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Passing linger.ms as a string.

Using incorrect units or types for buffer.memory and batch.size.

All three properties require numeric values: buffer.memory and batch.size in bytes, linger.ms in milliseconds.
