5. Chunk Loop

<p><strong>Chunk Loop</strong></p><p>This workflow implements an example of a chunk loop using the <em>Chunk Loop Start</em> node. The chunk loop processes the entire data table once, however, it processes the rows in pre-defined groups (so-called <em>chunks</em>). Processing smaller chunks of data at a time speeds up the execution time. The chunk size (i.e., the number of rows to be processed per iteration) can be defined in the <em>Chunk Loop Start</em> node.</p><p>The goal of this workflow is similar to the workflow "1. Counting Loop": Generate fake data with 3 clusters over 2 coordinates (x, y) and then shift the x-values (Universe_0_0) by adding the current iteration number to its value (e.g., x+0 in the first iteration, x+1 in the second iteration, etc.).</p>
