Refer to http://mysun.iteye.com/blog/1748473 one of the join series through Map-reduce The opening of this series begins with a look at the more extensive and popular central join algorithms currently in use in the database before you mention using Map-reduce to implement joins. They are nested loops join (Nested Loops join), sort Merge Join (Sort-merge join), and hash join (hash join).1.

In C ++, nested calls of functions are allowed, but nested definitions of functions are not allowed. For example: # Include Int swpint (int * a, int * B){Int C;C = *;* A = * B;* B = C;Return;}Void main (){Int e = 12;Int F = 89;Swpint ( E, F );Cout }This definition is correct, but a compilation error occurs if the following definition is used: # Include Void main (){Int e = 12;Int F = 89;Int swpint (int *

The conditional logic in the function makes it difficult for people to see the normal execution path.Use the Wei statement to show all special cases. Motivation: conditional expressions are usually expressed in two forms. 1. All branches are normal. Second, only one of the answers provided by the conditional expressions is normal, and others are uncommon. These two types of conditional expressions have different purposes. If the two branches are normal, you should use the form such as if ...
