yunfengzhou-hub opened a new pull request, #27163:
URL: https://github.com/apache/flink/pull/27163
## What is the purpose of the change
This issue aims to support configuring Model Function's behavior when the
remote requests failed, so as to better adapt to different use cases like
debugging or production.
## Brief change log
Adds support for the following error handling strategies
- retry: Retry sending the request. The retrying behavior is limited by
retry-num, retry-fallback-strategy, retry-backoff-strategy and
retry-backoff-base-interval.
- failover: Throw exceptions and fail the Flink job.
- ignore: Ignore the input that caused the error and continue. The error
itself would be recorded in log.
## Verifying this change
Added unit tests in ModelFunctionErrorHandlingStrategyTest to cover the
newly introduced functions.
