What this PR does / why we need it:

When a source created timestamp shares a name with a request column, Dask historical retrieval can read the request value instead. This can include a backfill created after the query time or remove a request column from the result.

Keep the source timestamp under a temporary name that cannot collide with request or feature columns. Regression tests cover timestamp filtering, preserved request data and multiple feature views.

Which issue(s) this PR fixes:

No existing issue.

Checks

  • I've made sure the tests are passing.
  • My commits are signed off (git commit -s)
  • My PR title follows conventional commits format

Testing Strategy

  • Unit tests
  • Integration tests
  • Manual tests
  • Testing is not required for this change

Focused tests and neighboring Dask tests pass, along with scoped Ruff and mypy checks. The regression uses local Parquet files through the public FeatureStore API.

Sorry, something went wrong.
