Improving the grouping aggregation capability depends on the following key features:</p>

<ul id="css_01_0173__ul1738395615311"><li id="css_01_0173__li638310569310">Sorting key: Data is stored in sequence based on the sorting key.</li><li id="css_01_0173__li10383856136">Clustering key: It is contained in the sorting key. Data is clustered based on the clustering key.</li></ul>

<p id="css_01_0173__p1738311563317">In the case of data clustering, enhanced aggregation uses the vectorization technology to process data in batches, improving aggregation performance.</p>
