Does Kafka support data compression and message transactions?

Kafka supports data compression and message transactions.

Data compression: Kafka offers data compression functionality, allowing messages to be compressed at the producer and consumer ends to reduce the amount of data transmitted over the network and save storage space. Kafka supports multiple compression algorithms, including gzip, snappy, and lz4.

Message transactions: Kafka introduces transactional support, allowing producers to commit a group of message transactions when sending messages, either all successfully committed or all rolled back. This ensures the atomicity and consistency of messages, while also providing a reliability guarantee for messages.
