<span class="text">Why Use This Approach?</span>
</h3>
<p>This function resolves dependencies between migrations that span across different repositories.
The default <code class="inline">migrate/0</code> function migrates each repository independently, which may result in
migrations running in the wrong order when there are cross-repository dependencies.</p><p>Consider the following example (adapted from reality, not 100% accurate):</p><ul><li><strong>Migration 1</strong>: The PostgreSQL (PG) repository creates a table named <code class="inline">site_imports</code>.</li><li><strong>Migration 2</strong>: The ClickHouse (CH) repository creates <code class="inline">import_id</code> columns in <code class="inline">imported_*</code> tables.</li><li><strong>Migration 3</strong>: The PG repository runs a data migration that utilizes both PG and CH databases,
reading from the <code class="inline">import_id</code> column in <code class="inline">imported_*</code> tables.</li></ul><p>The default <code class="inline">migrate/0</code> would execute these migrations by repository, resulting in the following order:</p><ol><li>Migration 1 (PG)</li><li>Migration 3 (PG)</li><li>Migration 2 (CH)</li></ol><p>This sequence would fail at Migration 3, as the <code class="inline">import_id</code> columns in the CH repository have not been created yet.</p><p><a href="#interweave_migrate/0"><code class="inline">interweave_migrate/0</code></a> addresses this issue by consolidating all pending migrations into a single, ordered queue:</p><ol><li>Migration 1 (PG)</li><li>Migration 2 (CH)</li><li>Migration 3 (PG)</li></ol><p>This ensures all dependencies are resolved in the correct order.</p>
