Preface Spring Data Redis Project,the spring concept was applied to develop a solution for data storage using key-value forms。 We (officially) provide a "Template", this is a high-level abstraction to send and receive messages. You're going to notice it.support for JDBC with the spring framework is somewhat similar。 Why choose Spring Data Redis? Spring Framework is the all-stack Java/jee application framework that leads the trend. It provides a lightweight container, a non-intrusive programming

There is no need to write a user name and password in the connection string, which in some way improves securit

SdramSDRAM (Synchronous dynamic random access memory) is synchronous, which means that the memory work requires a step clock, the internal command is sent and the data is transmitted as a benchmark Dynamic means that the storage array needs constant refresh to ensure that data is not lost, and stochastic means that the data is not stored linearly, but the data is read and written by the specified address. The current 168-wire 64bit bandwidth memory basically uses SDRAM chip, operating voltage 3.

that determine the performance of a group of memory. What does this mean? In fact, it is not difficult to really understand, and it is also very easy to calculate. The total memory bandwidth we just mentioned is actually the maximum data capacity that can be transferred within one second in an ideal situation. The formula is also very simple: total memory bandwidth (Mbytes) = maximum clock speed (MHz) x bus width (BITs) X number of data segments per clock/8. Let's explain it. It is best to unde
