fvaleri opened a new pull request, #21471: URL: https://github.com/apache/kafka/pull/21471
This patch rejects share consumer group IDs containing ':' to prevent `SharePartitionKey` parsing failure. The `SharePartitionKey` format (`groupId:topicId:partition`) breaks when the group ID itself contains ':', causing silent consumption failure. We apply a minimal targeted fix (colon-only restriction) to avoid breaking existing group naming conventions. This is validated on both client and broker to cover old clients without the check. -- This is an automated message from the Apache Git Service.
