Review Comment:
@chia7712 @AndrewJSchofield
I have modified the current implementation by reusing
offsetsUtils.parseTopicPartitionsToReset(). However, when attempting to pass a
non-existent topic-partition (e.g., topicA:999), a TimeoutException is thrown
as shown below:
`Caused by: java.util.concurrent.ExecutionException:
org.apache.kafka.common.errors.TimeoutException:
Call(callName=listOffsets(api=METADATA), deadlineMs=1753150292432,
tries=73308, nextAllowedTryMs=1753150293436)
timed out at 1753150292436 after 73308 attempt(s)`
This behavior is identical when resetting offsets for a non-existent
topic-partition for a consumer group. I think maybe we could create a new issue
to address this scenario, as the current implementation does not handle invalid
topic-partitions gracefully. I wonder what you think?
