		<description><![CDATA[I often get asked why CloverETL offers two sort components instead of just one and what’s the right key for determining which one is better for a particular purpose.

The reason for having two sort components in CloverETL is simply to keep things as easy as possible. Since the inner natures of ExtSort and FastSort are quite different it would be really difficult to implement a nice and clean universal one.

Luckily, the decision is simple and straightforward. In case you can dedicate enough system resources (CPU cores and/or memory) for the graph doing the sorting, FastSort is the clear option. On the other hand, if you’re short on resources and want a more conservative behavior, pick ExtSort which will give you steady performance at minimum system requirements. <a href="http://blog.cloveretl.com/sorting-data-extsort-vs-fastsort">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>
