-Data skew can cause unnecessary data movement or resource bottlenecks when running your workload. Advisor will detect distribution data skew greater than 15% and recommend that you redistribute your data and revisit your table distribution key selections. To learn more about identifying and removing skew, see [troubleshooting skew](https://docs.microsoft.com/azure/sql-data-warehouse/sql-data-warehouse-tables-distribute#how-to-tell-if-your-distribution-column-is-a-good-choice).
