# Limit rows while you build

> <p id="">When building in Parabola, there are times when you want to process <em id="">some </em>data, but not necessarily <em id="">the entire</em> dataset — like when you’re setting up an API call, joining large datasets, or<a id="" href="http://parabola.io/updates/ai-powered-steps-now-in-parabola"> using an AI transform</a>.</p><p id="">With the latest upgrade to the "Limit rows" step, you can choose to limit your dataset <em id="">just while you build</em> — but remove the limit and use the entire dataset when the Flow actually runs. That means no more waiting on thousands of API calls or a complex "Find overlap" step while you build.&nbsp;</p><p id="">Check it out and let us know what you think! </p>
