**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** The N+1 query problem in `listConsumerGroups()` is a valid performance concern. Calling `enrichGroupWithConnectionInfo()` for every group results in 2N admin API calls, which scales poorly for clusters with many consumer groups. **Root Cause:** `enrichGroupWithConnectionInfo()` makes 2 blocking admin calls per group (`examineConsumerConnectionInfo` + `examineConsumeStats`) without batching or parallelism. **Impact:** For 100 groups → 200 sequential admin calls, potentially timing out the HTTP request. **Severity:** High — directly affects dashboard usability at scale. **Suggested fix:** Batch the admin calls or use parallel execution (e.g., `CompletableFuture`) to reduce latency from O(N) to O(1) round-trips. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
