Fixes #1098

Problem

process_freshness_result reads max_loaded_at_time_ago_in_s from result_dict.age. dbt-core's freshness result has age, but the result dbt v2 passes to the on-run-end hook does not; it has the value as max_loaded_at_time_ago_in_s (the sources.json name). So every dbt v2 row in dbt_source_freshness_results gets a null max_loaded_at_time_ago_in_s, which hides the freshness details in the report and shows "Time Elapsed: N/A" in alerts.

Fix

A new macro, get_freshness_result_age, uses age when it is set and falls back to max_loaded_at_time_ago_in_s otherwise. dbt-core results are unchanged.

Test

• test_get_freshness_result_age calls the new macro with dbt-core-shaped (age) and dbt-v2-shaped (max_loaded_at_time_ago_in_s, no age) results, so the dbt v2 fallback is covered on every target. It passed on all targets in CI.
• Checked by hand with dbt v2 2.0.11 on BigQuery, running dbt source freshness with the package installed from this branch's first commit (the same fallback, inline before it moved into get_freshness_result_age). The new row got max_loaded_at_time_ago_in_s = 88.0 (snapshotted_at - max_loaded_at ≈ 88.5 s), where rows from 0.26.1 in the same table have null.
• get_freshness_result_age also checked locally with dbt-core 1.12.6 on DuckDB (run-operation), with the same inputs as the test.

Unrelated to this fix, but found along the way: test_source_freshness_results doesn't actually exercise source freshness on several targets. Its source points at target.schema while the seed lands in target.schema plus the pytest-xdist worker suffix, and its "UPDATE_TIME"::timestamp cast isn't valid T-SQL. So dbt source freshness fails with a runtime error and stores a runtime-error row, which passes the test's row-exists check. Asserting that the row has max_loaded_at_time_ago_in_s failed on DuckDB, Postgres, SQL Server, Vertica, Trino, Dremio and Spark, so I left that test unchanged here.

Summary by CodeRabbit

Summary

• Bug Fixes
  • Source freshness results now include the elapsed time since data was last loaded when the standard age value is unavailable. Results retain timing information when it is provided directly, and support alternate dbt result formats.
  • Freshness checks now accommodate timestamp formats used by Dremio, SQL Server, and PostgreSQL, helping ensure elapsed-time values are available across these platforms.

Walkthrough

The source freshness macro now falls back to max_loaded_at_time_ago_in_s when age is absent. The integration test checks that each returned source freshness result has a non-null value.

Changes: Source freshness age

Layer / File(s)	Summary
Select and validate freshness age macros/edr/dbt_artifacts/upload_source_freshness.sql, integration_tests/tests/test_dbt_artifacts/test_artifacts.py	process_freshness_result uses age when present and otherwise uses max_loaded_at_time_ago_in_s. The integration test asserts that each result has a non-null max_loaded_at_time_ago_in_s value.

Old error rows can cause a freshness integration test to fail on reruns without initialization. Normal CI uses isolated schemas, so this is a bounded test-workflow risk.

Explanation

[#1098] process_freshness_result now calls get_freshness_result_age. The helper preserves age when present and falls back to max_loaded_at_time_ago_in_s when age is absent or null. Tests cover dbt-core values, the dbt-v2 field, a null age, and an empty input. The source-freshness integration test also asserts that stored ages are non-null. The PR description reports a dbt v2 BigQuery check with the expected stored value.

Test the Fusion fallback.

This test skips Fusion at Line 146, so the assertion does not exercise the new fallback. Add a test with a Fusion-shaped result that has no age, and assert that the stored value matches max_loaded_at_time_ago_in_s.

Limit the query to the current freshness run.

With --skip-init, a previous runtime-error row remains in the append-only table. Because test_id is stable, the new assertion checks that row and fails even when the current run succeeds. Filter by the current invocation or clear matching rows before the run. (raw.githubusercontent.com)

@coderabbitai Re the outside-diff comment on test_artifacts.py (filtering the freshness assertion to the current invocation): not applicable. Each test session clears the environment first (env.clear() in conftest.py, which drops the Elementary and test schemas before env.init() rebuilds them), and this test runs once per session, so dbt_source_freshness_results only ever holds rows from the current run. The only way to keep older rows is a manual local --skip-init run, which affects every artifact test in this file the same way.

@grindheim You’re right. The session fixture clears and rebuilds the schemas on non-Dremio targets, and the assertion already filters by the test-specific unique_id. I withdraw the request for an invocation filter.

For completeness, Environment.clear() also skips Dremio, which uses a Docker environment.
