G0 D5: queryd DuckDB SELECT over Parquet via httpfs · 4 scrum fixes
Phase G0 Day 5 ships queryd: in-memory DuckDB with custom Connector
that runs INSTALL httpfs / LOAD httpfs / CREATE OR REPLACE SECRET
(TYPE S3) on every new connection, sourced from SecretsProvider +
shared.S3Config. SetMaxOpenConns(1) so registrar's CREATE VIEWs and
handler's SELECTs serialize through one connection (avoids cross-
connection MVCC visibility edge cases).
Registrar.Refresh reads catalogd /catalog/list, runs CREATE OR
REPLACE VIEW "name" AS SELECT * FROM read_parquet('s3://bucket/key')
per manifest, drops views for removed manifests, skips on unchanged
updated_at (the implicit etag). Drop pass runs BEFORE create pass so
a poison manifest can't block other manifest refreshes (post-scrum
C1 fix).
POST /sql with JSON body {"sql":"…"} returns
{"columns":[{"name":"id","type":"BIGINT"},…], "rows":[[…]],
"row_count":N}. []byte → string conversion so VARCHAR rows
JSON-encode as text. 30s default refresh ticker, configurable via
[queryd].refresh_every.
Cross-lineage scrum on shipped code:
- Opus 4.7 (opencode): 1 BLOCK + 4 WARN + 4 INFO
- Kimi K2-0905 (openrouter): 2 BLOCK + 2 WARN + 1 INFO
- Qwen3-coder (openrouter): 2 BLOCK + 1 WARN + 1 INFO
Fixed (4):
C1 (Opus + Kimi convergent): Refresh aborts on first per-view error
→ drop pass first, collect errors, errors.Join. Poison manifest
no longer blocks the rest of the catalog from re-syncing.
B-CTX (Opus BLOCK): bootstrap closure captured OpenDB's ctx →
cancelled-ctx silently fails every reconnect. context.Background()
inside closure; passed ctx only for initial Ping.
B-LEAK (Kimi BLOCK): firstLine(stmt) truncated CREATE SECRET to 80
chars but those 80 chars contained KEY_ID + SECRET prefix → log
aggregator captures credentials. Stable per-statement labels +
redactCreds() filter on wrapped DuckDB errors.
JSON-ERR (Opus WARN): swallowed json.Encode error → silent
truncated 200 on unsupported column types. slog.Warn the failure.
Dismissed (4 false positives):
Qwen BLOCK "bootstrap not transactional" — DuckDB DDL is auto-commit
Qwen BLOCK "MaxBytesReader after Decode" — false, applied before
Kimi BLOCK "concurrent Refresh + user SELECT deadlock" — not a
deadlock, just serialization, by design with 10s timeout retry
Kimi WARN "dropView leaves r.known inconsistent" — current code
returns before the delete; the entry persists for retry
Critical reviewer behavior: 1 convergent BLOCK between Opus + Kimi
on the per-view error blocking, plus two independent single-reviewer
BLOCKs (B-CTX, B-LEAK) that smoke could never have caught. The
B-LEAK fix uses defense-in-depth: never pass SQL into the error
path AND redact known cred values from DuckDB's own error message.
DuckDB cgo path: github.com/duckdb/duckdb-go/v2 v2.10502.0 (per
ADR-001 §1) on Go 1.25 + arrow-go. Smoke 6/6 PASS after every
fix round.

# D5 smoke — proves the Day 5 acceptance gate end-to-end.
|
||||
#
|
||||
# Validates:
|
||||
# - Ingest CSV via D4 → catalog manifest registered
|
||||
# - queryd starts AFTER ingest; initial Refresh picks up the dataset
|
||||
# - POST /sql with SELECT count(*) FROM <name> → matches CSV row count
|
||||
# - POST /sql with SELECT * FROM <name> LIMIT 3 → rows have expected
|
||||
# column names + types + values
|
||||
# - Re-ingest same CSV → updated_at bumps → next Refresh re-creates
|
||||
# the view (we restart queryd to verify the fresh-side path works)
|
||||
# - Schema-drift CSV ingest → catalogd 409s → queryd's view stays
|
||||
# pointing at the original (no DuckDB session corruption)
|
||||
#
|
||||
# Requires storaged + catalogd + ingestd + queryd binaries. MinIO at
|
||||
# :9000 with bucket lakehouse-go-primary already created (D2/D4 setup).
