Have a nice smileAsk questionsHow to use Java to generate serial numbers while supporting configurable and high concurrency???solve the problemSuppose your project has integrated the caching technologyIf you have a certain Java foundationIf......The following code implements a high-concurrency, configurable, high-efficiency serial number generator, can be used fo
for database applications, a proper serial number generator is very useful, with this function, we can conveniently assign values to the ID field (primary key) of the newly added record. Of course, we can also use the primary key of the Identity type. However, if there is a parent-child relationship record at the same time, therefore, assigning parent_id to a sub-record is inconvenient. We must first Insert
MyCAT global serial number
When database/table sharding is implemented, the auto-increment primary key of the database cannot be globally unique. Therefore, MyCat provides global sequence and multiple implementation methods including local configuration and database configuration.
Local file Mode
Principle: in this way, MyCAT configures the sequence to the file. When the sequence configuration is used, MyCA

When asked whether the recent Windows Vista OEM version of the cracked can be blocked, Mr. Anderson replied that this phenomenon is in fact unexpected. At present, Microsoft does not take any action to this crack way. But the OEM hack will be blocked when Windows Vista SP1 is released in the second half of this year.
Because Windows Vista SP1 will integrate the validator for Windows Vista product key, all vendors ' Windows Vista OEM version of universal installation key will
