var QueryTestsQueryTmpl = template.Must(template.New("QueryTestsQuery").Parse(`
	WITH Tests as (
		SELECT DISTINCT TestId, SubRealm IN UNNEST(@subRealms) as HasAccess
		FROM TestRealms

	)
	SELECT TestId FROM Tests
	WHERE HasAccess
	ORDER BY TestId ASC

`))

The query is written in a way to force spanner NOT to put `SubRealm IN UNNEST(@subRealms)` check in Filter Scan seek condition, which can significantly increase the time it takes to scan the table.
