Add biquery query parameter option to support parametrize query

[i05nagai]

Addresses: #29382
Also addresses: #25096

Description

This PR supports QueryParameter for BigQueryIO in Go.
The type of bigquery.QueryParameter.Value is any so encoding/decoding should preserve the types in any.
To preserve type information, I've implemented it with encoding/gob under the following limitations:

• user-defined struct is not supported
• user-defined scalar type (e.g. type Counter int64)

bbigquery.QueryParameter.Value supports both types. See https://github.com/googleapis/google-cloud-go/blob/bigquery/v1.79.0/bigquery/params.go#L323.

Another possible approach is to implement a similar conversion logic to that implemented in paramValue by converting user-defined types to bigquery.QueryParameterValue explicitly.
This solution requires us to maintain the same conversion logic defined internally in the bigquery pkg. This seems over-complicated for now. But we can extend the implementation to add the conversion logic in the encodeQueryParameter function later.

Tests

I successfully ran integrated tests with

go test -v ./test/integration/io/bigqueryio \
      --runner=direct \
      --project=${PROJECT_ID} \
      --bq_dataset=${DATASET_ID}

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enables parameterized queries for BigQueryIO in the Go SDK. By allowing users to pass query parameters, it improves security and flexibility when interacting with BigQuery. The changes include the necessary infrastructure to serialize these parameters for execution within the Beam pipeline, alongside updates to integration test utilities to better support project-specific configurations.

Highlights

• Parameterized Query Support: Added support for parameterized queries in BigQueryIO by introducing WithQueryParameters and handling the serialization of bigquery.QueryParameter objects.
• Serialization Infrastructure: Implemented new encoding and decoding logic for query parameters using JSON to ensure compatibility with Beam's serialization requirements.
• Integration Test Improvements: Updated integration test helpers to explicitly pass project IDs and improved table validation logic to ensure more reliable test execution.

Code Review

This pull request introduces support for parameterized queries in the Go SDK's BigQuery IO connector, adding a new WithQueryParameters option, serializing parameters during pipeline execution, and updating integration tests. The reviewer feedback is highly constructive and identifies critical issues: JSON serialization will cause type loss for query parameters (e.g., converting integers to floats), which can be resolved by using gob encoding; decoding will fail on empty parameters without a guard check; tests should be expanded to cover numeric types; and encoding should be skipped when no parameters are provided to avoid overhead.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Errant formatting change?

[i05nagai]

Thank you for reviewing!
I ran go fmt against this file. The formatting matches go fmt.
As far as I can tell, go fmt runs only against sdks/go/pkg/beam in CI: https://github.com/apache/beam/blob/master/.github/workflows/go_tests.yml#L61

I can do either

• (1) Revert this formatting
• (2) Or create another issue and a dedicated PR to update the go fmt check to include all Go files

[lostluck]

Gofmt aligns comments vertically when part of consecutive lines in the same block, so the new formatting is correct. I wouldn't worry about trying to fix it.

[lostluck]

LGTM. Just one typo fix. I'd make it myself but I'm phone only at the moment.
