DEFAULT KEY VS EMPTY KEY

[@devendrapatel6389]

thanks you. Very nicely explained both the points

[@pankajkumaram]

Glad it was helpful!

Even if we dont specify empty key, we have to explicitly specify by key field addition, then what is the usecase of adding empty key

[@pankajkumaram]

Not necessary to specify explicitly. Without explicit key it takes standard key i.e. combination of character data type fields
