alpreu opened a new pull request #18319:
URL: https://github.com/apache/flink/pull/18319
## What is the purpose of the change
testRetryComittableORetriableError is taking over an hour on CI runs. We
want to speed up the test.
The KafkaProducer doc states:
````
* <p>
* To enable idempotence, the <code>enable.idempotence</code> configuration
must be set to true. If set, the
* <code>retries</code> config will default to <code>Integer.MAX_VALUE</code>
and the <code>acks</code> config will
* default to <code>all</code>. There are no API changes for the idempotent
producer, so existing applications will
* not need to be modified to take advantage of this feature.
* </p>
```
The issue is therefore that we retry MAX_VALUE times. This PR sets the
number of retries to 3.
## Brief change log
- set ProducerConfig option 'retries' to 3.
## Verifying this change
This change added tests and can be verified as follows:
* CI run for test_ci_build kafka_gelly should be significantly faster.
Compare with previous runs (> 1hr)
* Log of producer config values should show 'retries = 3'
