Describe your changes:

Fixes #26077
Additional changes: Paginate workspace fetch filter in limit of 10 instaed of 20 to keep node limit under 100 in single API request.

Type of change:

  • Bug fix
  • Improvement
  • New feature
  • Breaking change (fix or feature that would cause existing functionality to not work as expected)
  • Documentation

Checklist:

  • I have read the CONTRIBUTING document.
  • My PR title is Fixes <issue-number>: <short explanation>
  • I have commented on my code, particularly in hard-to-understand areas.
  • For JSON Schema changes: I updated the migration scripts or explained why it is not needed.

Summary by Gitar

  • Fixed column name length limits:

    • Applied truncate_column_name() across 8+ dashboard sources (PowerBI, Looker, MicroStrategy, QlikSense, QuickSight, Sigma, Superset, Tableau) to enforce 256-character maximum
    • Preserved original names in displayName for display purposes; truncation affects only the name field

  • Reduced Power BI API batch size:

    • Changed MAX_PROJECT_FILTER_SIZE from 20 to 10 to comply with Power BI Admin API's 100-node OData filter expression limit
    • Added comprehensive documentation of node cost calculations for different filter types in new constants.py file

  • Updated test coverage:

    • Adjusted pagination tests to validate batch size of 10 instead of 20
    • Added test for column name truncation exceeding 256-character boundary

This will update automatically on new commits.

Code Review 👍 Approved with suggestions 2 resolved / 3 findings

Clean, consistent fix for column name truncation across 8+ dashboard sources with well-documented constants refactoring. One minor gap: the pagination test doesn't verify excludes on all batches.

💡 Edge Case: Test missing excludes assertion for third batch

📄 ingestion/tests/unit/topology/dashboard/test_powerbi.py:997

The test test_paginate_project_filter_pattern_with_includes_and_excludes validates that excludes are preserved across paginated batches, and its docstring explicitly states "Excludes should be preserved across all paginated batches." However, with the new batch size of 10, 25 includes now produce 3 batches instead of 2, but the test only asserts result[0].excludes and result[1].excludes — it does not verify result[2].excludes.

This is a gap in test coverage: if the pagination logic had a bug where the last batch didn't carry excludes, this test wouldn't catch it.

Suggested fix 
        self.assertEqual(result[0].excludes, excludes)
        self.assertEqual(result[1].excludes, excludes)
        self.assertEqual(result[2].excludes, excludes)
✅ 2 resolved
✅ Quality: Import statement placed after module-level logger assignment

📄 ingestion/src/metadata/ingestion/source/dashboard/powerbi/metadata.py:93
The constants import block (lines 93-101) is placed after logger = ingestion_logger() on line 91. This happened because the old code defined inline constants at that position, and the refactoring replaced them with an import in-place rather than moving it up with the other imports.

While Python allows this, it violates PEP 8 convention (all imports at the top of the file) and will likely be flagged by isort or similar linting tools. It also makes the import harder to find when scanning the file's dependency list.

✅ Quality: Stale docstrings reference old batch size of 20

📄 ingestion/src/metadata/ingestion/source/dashboard/powerbi/metadata.py:189 📄 ingestion/tests/unit/topology/dashboard/test_powerbi.py:939 📄 ingestion/tests/unit/topology/dashboard/test_powerbi.py:953
Several docstrings and comments still reference the old batch size of 20 after it was changed to 10:

  1. _paginate_project_filter_pattern docstring (line 189): says "paginate include filters if more then 20 filters"
  2. Test test_paginate_project_filter_pattern_includes_under_limit docstring (line 939): says "with include filters under the limit (20)" and "Should return a single batch" — but 15 items with batch size 10 actually returns 2 batches (the assertions are correct, but the docstring is wrong)
  3. Test test_paginate_project_filter_pattern_includes_at_limit docstring (line 953): says "exactly 20 include filters" — it does test 20 items, but the docstring describing the "at limit" behavior is misleading since the limit is now 10

These stale comments could confuse future developers about the actual batch size behavior.
