id="implementation-pattern">Implementation Pattern<a href="#implementation-pattern" class="hash-link" aria-label="Direct link to Implementation Pattern" title="Direct link to Implementation Pattern"></a></h3><p>The S3 source demonstrates the recommended pattern for isolating PySpark-dependent code. This pattern can be applied to ABS and other sources in future PRs.</p><p><strong>Architecture (currently implemented for S3 only):</strong></p><ol><li><strong>Main source class</strong> (<code>source.py</code>) - Contains no PySpark imports at module level</li><li><strong>Profiler class</strong> (<code>profiling.py</code>) - Encapsulates all PySpark/PyDeequ logic in <code>SparkProfiler</code> class</li><li><strong>Conditional instantiation</strong> - <code>SparkProfiler</code> created only when profiling is enabled</li><li><strong>TYPE_CHECKING imports</strong> - Type annotations use TYPE_CHECKING block for optional dependencies</li></ol><p><strong>Key Benefits:</strong></p><ul><li>✅ Type safety preserved (mypy passes without issues)</li><li>✅ Proper code layer separation</li><li>✅ Works with both standard and <code>-slim</code> installations</li><li>✅ Clear error messages when dependencies missing</li><li>✅ Pattern can be reused for ABS and other sources</li></ul><p><strong>Example structure:</strong></p><div class="language-python codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#bfc7d5;--prism-background-color:#292d3e"><div
