In our previous chapters, we&rsquo;ve explored Stoolap&rsquo;s unique architecture, from its robust storage engine to its powerful MVCC transactions. Now, it&rsquo;s time to pull back the curtain on one of the most intelligent components of any modern database: the <strong>Query Optimizer</strong>.</p> <p>Think of the Query Optimizer as the database&rsquo;s brilliant strategist. When you ask Stoolap a question using SQL, there are often many different ways to find the answer. Should it scan an entire table? Should it use an index? If multiple tables are involved, in what order should they be joined? The optimizer&rsquo;s job is to figure out the <em>most efficient</em> path to retrieve your data, minimizing resource usage and execution time.</p>
