Technical Field
The invention relates to the technical field of stored data access, in particular to an asynchronous stored data access method based on trusted computing and a using method thereof.
Background
Asynchronization: a communication mode is simple in equipment requirement. The standard communication interfaces provided by our PCs are asynchronous. The asynchronous parties do not need a common clock, i.e. the receiver does not know when the sender is sending, so there is a message in the message sent to prompt the receiver to start receiving, such as a start bit, and there is a stop bit at the end. Another meaning of asynchronous is asynchronous processing of computer multithreading. Asynchronous processing, as opposed to synchronous processing, does not block the current thread waiting for processing to complete, but allows subsequent operations until other threads will complete processing and call back to notify the thread. It should be clear here that asynchrony and multithreading are not the same concept.
As internet applications grow more and more, traffic volume has multiplied. This in turn leads to an increase in the amount of data at the geometric level. The application pressure is getting larger and larger, and the service performance and the availability of the application are seriously influenced by frequent read-write access to the database. For some systems with high real-time response requirements to access the database, the database access component cannot block the service of the client request for the data because of the need to support large-scale concurrent access and enable efficient response. The access of the database restricts the real-time processing performance of the system. It is necessary to perform asynchronous and batch processing on the read-write access of the database. The performance of an application program can be greatly improved by accessing an asynchronous database, and therefore, an asynchronous storage data access method based on trusted computing and a use method are provided.
