Auto House Data Platform architectureInternet Enterprise Data Warehouse construction is to use the bottom-up approach, or top-down approach. If you are an architect in the data division, how do you plan a data warehouse? At the 2015 China Database Technology conference, Gaohong from the Auto House User Intelligence Group introduced the Auto House platform archite

The MySQL default mode of operation is autocommit auto-commit mode. This means that unless a transaction is explicitly started, each query is executed automatically as a separate transaction. We can change whether the autocommit mode is auto-committed by setting the value of autocommit. You can view the current autocommit mode by using the following command.' autocommit ' ; +---------------+-------+| variab

I have been searching for it online for a long time. Some people say that uuid is better, that is, it is easier to merge data into sub-databases and sub-tables, and some people say that auto-increment is better, when there is more data in the table, the performance is much better than the uuid. What is better? Are there any great gods in the real production environment to give a complete... I have been searching for it online for a long time. Some peo
1 Auto keywordBefore we introduce, let's start by understanding a new keyword auto.In C++11, if the compiler can infer the type of a variable when it is declared, then instead of having to put the variable type before the declaration, you can declare the variable directly with auto:int x = 4;In other words, the above declaration statement can be replaced by the following statement:auto x = 4;Of course, this is certainly not the fundamental purpose of
1. More use Auto instead of explicit type declaration
Reduce large segment declarations to auto
For example:TypeName Std::iterator_traits= *b;
Use Auto to prevent variables from being initialized
For example:int // correct, but not initialized // error, no initialization 3 // correct, declare and initialize
Automatic type
