PolyBase row width limit increased in SQL Data Warehouse

31 March 2017

The latest release of PolyBase in Azure SQL Data Warehouse increases the row width limit from 32 KB to 1 MB. So you can now ingest your wide rows directly from Azure Blob storage or Azure Data Lake Store into SQL Data Warehouse.

The row limit is determined by the size of the data when it's in UTF-16 encoding rather than the row width of the data in the file.

For more information about the feature, see the blog entry.
