From 0b7f14c572a54ee6d5276154c330c0bbc02e07d1 Mon Sep 17 00:00:00 2001 From: Haiyuan Cao Date: Mon, 29 Jun 2026 13:26:18 -0700 Subject: [PATCH 1/4] feat(bigquery-analytics): otel correlation, custom_metadata allowlist, column projection Implements three BQAA plugin observability controls (GoogleCloudPlatform/BigQuery-Agent-Analytics-SDK#312/#320/#321): - #312 span-level Cloud Trace correlation: capture the ambient OTel span context at row-emission time (only when is_valid) into attributes.otel.*; span_id/parent_span_id stay the BQAA-internal execution tree. Corrects the stale "OpenTelemetry span ID" schema descriptions. Best-effort join key (an unsampled valid span is absent from Cloud Trace), not a foreign key; otel_parent_span_id deferred (not derivable from SpanContext alone). - #320 custom_metadata allowlist: custom_metadata_allowlist config (exact keys + explicit "a2a:*"-style prefixes) captures event.custom_metadata into attributes.custom_metadata.* on every row emitted from the source Event (including AGENT_RESPONSE, which did not read custom_metadata before), through the existing safety pipeline (truncation, sensitive-key redaction, circular-ref handling, is_truncated). The built-in a2a:* path is unchanged. - #321 physical column projection: payload_column_denylist (denylist-first, scoped to content/content_parts/attributes/latency_ms; identity/correlation columns are protected and raise ValueError). Applied schema-first so the BQ schema, Arrow schema, row dict, and views stay consistent; projection-aware views drop derived columns that reference a denied payload column. Also broadens the is_truncated column description to cover content or metadata payload truncation. Adds 25 unit tests; full plugin suite green (287 passed, 6 skipped). --- .../bigquery_agent_analytics_plugin.py | 218 ++++++++++++- .../test_bigquery_agent_analytics_plugin.py | 296 ++++++++++++++++++ 2 files changed, 506 insertions(+), 8 deletions(-) diff --git a/src/google/adk/plugins/bigquery_agent_analytics_plugin.py b/src/google/adk/plugins/bigquery_agent_analytics_plugin.py index 36d92bf781d..286b29507c9 100644 --- a/src/google/adk/plugins/bigquery_agent_analytics_plugin.py +++ b/src/google/adk/plugins/bigquery_agent_analytics_plugin.py @@ -36,6 +36,7 @@ os.environ.setdefault("GRPC_ENABLE_FORK_SUPPORT", "1") import random +import re import time from types import MappingProxyType from typing import Any @@ -606,6 +607,19 @@ class BigQueryLoggerConfig: views like ``v_llm_request``.

Adds 5 tests (denylist-relaxed upgrade, current-and-complete no-op, fail-fast rejection, attributes-denied otel skip).

And denying both content and content_parts still did the full parse/offload for a row that keeps neither payload column. - When content_parts is denied, do not construct the GCS offloader (large / binary content is kept inline + truncated instead of uploaded); log a warning so the disabled offload is visible. - When both content and content_parts are denied, skip content parsing entirely (no inline summary, no parts, no offload).
