**What** This PR updates the behavior of client.id assignment when a user provides a custom value via override configs in Kafka Connect. **Why** Currently, if a user overrides the client.id, all tasks or consumers inherit the same client ID. While this doesn't cause an immediate failure in Kafka, it leads to the following issues: - Metrics and logs are merged or overwritten, making observability inaccurate. - Quotas and throttling may be applied incorrectly. - Debugging becomes harder due to lack of per-task identity. **According to Kafka core behavior**, client.id should be unique per client instance for proper tracking and diagnostics. **How** This PR appends the **task number** to the user-provided client.id to ensure uniqueness across tasks. **For example:** - User provides: client.id=my-custom-client - Final client.id used by task 2: my-custom-client-2 **This approach:** - Respects the user’s original intent in naming - Guarantees unique client.id values per task - Improves metrics, logging, and debugging consistency -- This is an automated message from the Apache Git Service.
