extent storage capacity of varchar(8000) to varchar(max)

The maximum string length of 8000 is often considered too short to store longer descriptive data or embed a JSON value within a text field in a database. Dividing the data into smaller chunks and store them across multiple text fields or in separate tables is unnecessarily cumbersome.da...
