💡 Hint

Common Mistakes

Using 'gz' instead of 'gzip' as the compression type.

Forgetting to put the compression type in quotes.

Setting compression.type to gzip enables gzip compression for Kafka producer messages.

Complete the code to configure the Kafka producer to compress messages with snappy.

Kafka

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

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

💡 Hint

Common Mistakes

Using 'snip' or 'snap' instead of 'snappy'.

Confusing compression.type with other Kafka properties.

Setting compression.type to snappy tells Kafka to use Snappy compression for messages.

Fix the error in the code to enable lz4 compression for Kafka producer.

Kafka

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

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

💡 Hint

Common Mistakes

Using underscores or dashes in the compression type string.

Misspelling 'lz4' as 'lzfour'.

The correct string for LZ4 compression in Kafka is lz4. Other variants are invalid.

4fill in blank

hard

Fill both blanks to create a Kafka producer configuration that uses gzip compression and sets the batch size to 16384 bytes.

Kafka

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

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

💡 Hint

Common Mistakes

Using batch size as a string instead of an integer.

Mixing compression types and batch sizes.

Setting compression.type to gzip enables gzip compression. The batch.size property controls the batch size in bytes, here set to 16384.

5fill in blank

hard

Fill all three blanks to create a Kafka producer configuration that uses lz4 compression, sets batch.size to 50000, and enables idempotence.

Kafka

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

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

💡 Hint

Common Mistakes

Using numeric values as strings for batch.size.

Setting enable.idempotence to 'yes' or '1' instead of 'true'.

Using lz4 for compression, setting batch.size to 50000 bytes, and enabling idempotence with true configures the producer accordingly.
