Tuning a Kafka Producer

Configuring Kafka producers is a relatively simple process. The real challenge is knowing what configuration options to change in order to tune the producer for your use case. In this lab, you will have the opportunity to work hands-on with the process of tuning a Kafka producer. You will be presented with a few issues that can be addressed through configuration tuning. You will then need to determine what configuration changes to make in order to address these issues, and you will need to implement those changes in the producer.

Challenge

Implement the Configuration Changes in the Producer
1. Open the file:
```
vi src/main/java/com/linuxacademy/ccdak/producer/MemberSignupsProducer.java
```
2. Fix the issue with data loss by setting acks=all:
```
props.put("acks", "all");
```
3. Fix the out-of-order record issue caused by retries by setting max.in.flight.requests.per.connection=1:
```
props.put("max.in.flight.requests.per.connection", "1");
```
4. Increase the batch size by setting batch.size=65536:
```
props.put("batch.size", "65536");
```
5. Run your code to verify that it still works:
```
./gradlew run
```
