First, the architecture of the InnoDB storage engine is simply presented in a single diagram.As can be seen, the InnoDB storage engine has multiple blocks of memory that make up a large pool of memory, primarily responsible for the following tasks: Maintain multiple internal data structures that all processes/threads need access to Cache data on disk for quick reading and caching before disk fi

Allows routing to be routed on such high-speed Gigabit Ethernet. iSCSI technology is a new storage technology that combines existin

Stack is the most common data structure, which is characterized by a LIFO (last on First out) is also a special form of the list, so as with the chain list, there are two ways of storage, the first is the sequential storage stack, easy to read and write data, but the length of the stack must be fixed first, the second is a chain storage stack, Can not define the

HTML5 provides two new ways to store data on the client: localstorage - local persistent storage, next open browser data still exists sessionstorage -data store that exists only in one session, closing the browser data will be erased Note: 1) As long as the browser cookie is cleared, both storage data will be erased 2) for different sites, the data is stored in different regions, each

Storage and operation of integers in calculation, and storage of Integers The first digit of an integer indicates the symbol bit. 1 positive integer A positive integer is stored in binary format in a computer. For example: short s = 3;3 = 2 ^ 1 + 2 ^ 0 A short integer is generally two bytes, that is, 16 bits. Its storage method is as follows: 0 000 0011 Therefo

Summarize the differences between the three types of JavaScript data storage, javascript Data Storage SessionStorage, localStorage, and cookie:All are saved on the browser side and the same source. Differences between sessionStorage, localStorage, and cookie:Cookie data is always carried in the same source http Request (even if not required), that is, the cookie is transmitted back and forth between the bro

OverviewIn HTML5, a new localstorage feature is added, which is primarily used as a local store to solve the problem of insufficient cookie storage space (4k per cookie in the cookie). The 5M size is supported by the General browser in Localstorage.Localstorage The advantages1, Localstorage extended the 4K limit of cookies2, Localstorage will be able to store the first request data directly to the local, this is equivalent to a 5M size for the front-e

localstorage– data storage with no time limitsessionstorage– data storage for a session ——————Localstorage methodThe data stored by the Localstorage method has no time limit. Data is still available after the next day, the second week, or the following year.
