Kafka - Producers

Given this Kafka producer config snippet:

props.put("compression.type", "lz4");
props.put("batch.size", 16384);

What is the expected effect on message sending?

AMessages are sent uncompressed due to batch size

BProducer will throw a configuration error

CMessages are compressed using gzip regardless

DMessages are compressed using lz4 before sending

Step-by-Step Solution

Solution:

Step 1: Analyze compression.type setting
Setting "compression.type" to "lz4" means messages will be compressed with lz4 codec.
Step 2: Understand batch.size effect
Batch size controls message batch size but does not disable compression.
Final Answer:
Messages are compressed using lz4 before sending -> Option D
Quick Check:
compression.type = lz4 means lz4 compression [OK]

Quick Trick: compression.type controls codec, batch.size does not disable compression [OK]
