When we speak of skew in Teradata, we mean an uneven load on the AMP. Skewing is also present in Snowflake at the node level. Snowflake uses a method to minimize skew automatically: file stealing. When a worker process has finished its work (i.e., scanned its input files), it requests additional files from other worker tasks. The other worker tasks check how many input file sets they have left to process and pass them to the requesting worker task. This automatically balances the skew. This kind of skew optimization is not possible on a shared-nothing system like Teradata.
