Dear Michael, Thanks for the pointers.
I was looking at https://azure.microsoft.com/en-us/documentation/articles/data-lake-analytics-u-sql-get-started/ <https://azure.microsoft.com/en-us/documentation/articles/data-lake-analytics-u-sql-get-started/> and trying to understand the big picture from examples. So U-SQL is a dataflow scripting language, where the basic data model is a set of rows with C# types, and each step in the data flow is an expression that can mix (at many levels) SQL’s Select-from-where constructs with C# code. That’s what I understand at least. Let me know if I got it wrong. Seems very useful for expressing complex data transformations of all kinds, and it is still optimizable. Much more useful for “data science” (whatever this big word means..) then the series of SQL-wannabes languages from the NoSQL vendors. Thanks, best regards Dana > On Nov 2, 2015, at 4:56 PM, Michael Rys <[email protected] > <mailto:[email protected]>> wrote: > > No formal specification.
