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

So we need to have an efficient sparse matrix storage format. This article summarizes several typical formats: Coo,csr,dia,ell,hyb.(1) Coordinate (COO)This is the simplest of a format, each element needs t

Database Design-semi-structured storage and database structured storage Business scenario: the user fills in some documents, reports them, and approves them. There are several fields in the document that need statistics, and the business is not complicated. In a seemingly simple scenario, when the developer came up with the PDM design, I was shocked. There were nearly 70 tables, each of which had more than

The localstorage in the HTML5 local storage API is the same as sessionstorage in the usage method, except that Sessionstorage is emptied after the page is closed, and Localstorage is saved. Here we take localstorage as an example, briefly introduce the local storage of the next HTML5, and give some sample explanations for common problems such as traversal. Localstorage is the HTML5 locally stored API that a
