What are Kafka acknowledgments and how do they work?
Kafka acknowledgments are a mechanism that ensures messages are successfully received by consumers. They help in managing message delivery guarantees.
Can you explain the different types of acknowledgments in Kafka?
Sure! There are three types: 0 (no acknowledgment), 1 (leader acknowledgment), and all (all replicas must acknowledge). Each has different reliability levels.
What happens if a message is not acknowledged?
If a message is not acknowledged, it may be retried based on the producer's configuration, or it could be lost if the acknowledgment is set to 0.
How do acknowledgments affect message delivery performance?
Acknowledgments can impact performance; higher reliability settings may introduce latency, while lower settings can improve throughput.
