Practice - 5 Tasks

1fill in blank

easy

💡 Hint

Common Mistakes

Using too small batch size reduces throughput.

Using too large batch size increases latency.

The batch size is typically set to 16384 bytes (16 KB) for efficient batching.

2fill in blank

medium

Complete the code to set the compression type for the Kafka producer.

Kafka

props.put("compression.type", [1]);

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

A"gzip"

B"snappy"

C"none"

D"lz4"

💡 Hint

Common Mistakes

Using compression type without quotes causes errors.

Choosing unsupported compression types.

Setting compression.type to "gzip" enables gzip compression for messages.

3fill in blank

hard

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

Kafka

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

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

A"5"

💡 Hint

Common Mistakes

Using string instead of integer causes runtime errors.

Using long literals is unnecessary here.

linger.ms expects an integer value, so 5 without quotes is correct.

4fill in blank

hard

Fill both blanks to create a producer config with batch size and compression type.

Kafka

props.put("batch.size", [1]);
props.put("compression.type", [2]);

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

💡 Hint

Common Mistakes

Mixing up batch size and compression values.

Using strings for batch size.

Batch size is set to 16384 bytes and compression.type to "gzip" for good performance.

5fill in blank

hard

Fill all three blanks to configure batch size, linger.ms, and compression type.

Kafka

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

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

💡 Hint

Common Mistakes

Using strings for numeric values.

Choosing unsupported compression types.

Batch size is 16384 bytes, linger.ms is 10 ms, and compression.type is "snappy" for balanced performance.
