to locking. Multiple tables will be constrained by InnoDB internal widget (different tables will be protected by different MDL locks, so the link bottlenecks in MDL will be reduced). But again, it depends on the size of the workload--a much more read-only work measurement will perform better in MySQL5.6 (such as Sysbench Oltp_ro), while queries with fewer and faster workloads (such as Sysbench point-selects ( Using a foreign key to get a record) will make all links difficult and can only be mea

In this case, the connection bottleneck in MDL is reduced ). However, it also depends on the workload.

Jszip is a javaScript tool that can create, read, and modify. zip files. In a Web application, you need to get resources from a Web server, and if you can merge all of your resources into a single. zip file, you only need to make one request at a time, which reduces the pressure on the server and speeds up the rendering of your Web application. Discuss how the next jszip can be combined with the HT topology application today. Let's take a look at thi

I. Brief introduction to the hash table (Hashtable) In. in the. NET Framework, Hashtable is System. A container provided by the Collections namespace is used to process and present key-value pairs similar to key/value. The key is usually used for quick search, and the key is case sensitive; value is used to store the value corresponding to the key. In Hashtable, key/value pairs are of the object type, so Hashtable can support any type of key/value pairs. Ii. Simple operations on Hash Tables Add
