Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Query Troubleshooting ## Causes | ID | Cause | Evidence | |----|-------|----------| | A | Client timeout too small | `query_timeout` vs Profile wall | | B | Planner | `Nereids cost too much time` / `nereids_timeout_second` | | C | BE compute (scan/join/spill) | Profile active ExecTime | | D | Exchange / brpc | WaitForData ≈ timeout; `failed to send brpc when exchange`; `[E1008]` on `:8060` | ## 10 min ```sql SET enable_profile = true; -- reproduce ``` ```bash ./scripts/doris-debug log-grep fe/log be/log --query-id "$QID" --pack planner ./scripts/doris-debug log-grep be/log --query-id "$QID" --pack exchange ./scripts/doris-debug audit-topk fe/log/fe.audit.log -k 20 --min-ms 5000 ``` Planner mitigation (session only): `SET disable_join_reorder=true;` for fat ETL joins; fix stats with `ANALYZE`. ## Cause C — BE compute (scan/join/spill) When Profile shows high active ExecTime (not Wait\*), route to **doris-profile-reader** for deep Profile analysis: > **Skill routing**: If `doris-profile-reader` is available, invoke it with the query's Profile to identify which operator (scan/join/agg/spill) dominates.

How to install
mdr add apache/doris-skills/doris-debug-query@sha256:675cd25e2b201227The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
