Assertions with Python SDK</h1><div></div><p>This guide specifically covers how to use the DataHub Cloud Python SDK for <strong>bulk creating smart assertions</strong>, including:</p><ul><li>Smart Freshness Assertions</li><li>Smart Volume Assertions</li><li>Smart Column Metric Assertions</li></ul><p>This is particularly useful for applying data quality checks across many tables and columns at scale.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="why-would-you-use-bulk-assertion-creation">Why Would You Use Bulk Assertion Creation?<a href="#why-would-you-use-bulk-assertion-creation" class="hash-link" aria-label="Direct link to Why Would You Use Bulk Assertion Creation?" title="Direct link to Why Would You Use Bulk Assertion Creation?"></a></h2><p>Bulk creating assertions with the Python SDK allows you to:</p><ul><li><strong>Scale data quality</strong>: Apply consistent assertions across hundreds or thousands of tables</li><li><strong>Automate assertion management</strong>: Programmatically create and update assertions based on metadata patterns</li><li><strong>Implement governance policies</strong>: Ensure all critical tables have appropriate data quality checks</li><li><strong>Save time</strong>: Avoid manually creating assertions one by one through the UI</li></ul><h2 class="anchor anchorWithStickyNavbar_LWe7" id="prerequisites">Prerequisites<a href="#prerequisites" class="hash-link" aria-label="Direct link to Prerequisites" title="Direct link to Prerequisites"></a></h2><p>You need:</p><ul><li>DataHub Cloud Python SDK installed (<code>pip install acryl-datahub-cloud</code>)</li><li>Valid DataHub Cloud credentials configured (server URL and access token with appropriate permissions)</li></ul><p>The actor making API calls must have the <code>Edit Assertions</code> and <code>Edit Monitors</code> privileges for the datasets at hand.</p><div class="theme-admonition theme-admonition-note alert alert--secondary admonition_LlT9"><div

to handle large scale operations. However, since writes are submitted asynchronously onto a Kafka queue, you may experience significant delays in the operations being applied. If you run into any issues, here are some tips that may help:</p><ul><li><strong>Consider running off peak</strong> to prevent causing spikes in Kafka lag for large bulk operations</li><li><strong>Before you re-run sync</strong> (i.e. to update), wait for GMS to complete processing the previous run to prevent inconsistencies and duplicating: i.e., check if last ingested item has reflected in GMS</li><li><strong>Monitor processing status</strong> through the DataHub UI or API to ensure operations complete successfully</li><li><strong>Process datasets in batches</strong> to avoid overwhelming the API</li><li><strong>Add delays</strong> between batch processing if needed</li></ul><h3 class="anchor anchorWithStickyNavbar_LWe7" id="5-testing-strategy">5.
