The mechanism used for optimistic locking is Cas,compare and Swap.First, what is CAsCas,compare and swap abbreviations, Chinese translation into comparison and exchange.We all know that before the Java language, concurrency has been widespread and has been used extensively in the server world. So hardware vendors have long been in the chip to add a large number of primitives until the concurrent oper
SSO stands for Single Sign On. SSO is used in multiple application systems. Users only need to log on once to access all mutually trusted application systems.
There are many SSO solutions, such as UTrust, HP Smart, and open-source CAS and Smart SSO, among which CAS is the most widely used.
