All the friends who have used Dede know that because Dede does not have the function of copying documents between columns in the background, only the function of moving documents (similar to cutting) is available ), however, I need to make multiple column list pages call this document. If you add each column, it will be exhausted. The secondary topic of Dede solves this problem. It allows a document to be called by the primary topic, or even by multiple secondary topics. The settings of the sec

decentralized database pressure. The business module is unclear, and a system with a higher coupling (table Association) degree is not suitable for this kind of splitting method. But the vertical splitting method does not completely solve all the pressure problems, such as having a 5000w order table, the pressure to operate the order library is still very large, such as we need to add (insert) a new data in this table, after the insert is completed, the database will re-index this table, 5000w

When the number of single-table records reaches millions to tens, the use of a table is necessary.Data segmentation can be physical, the data through a series of segmentation rules to distribute the data to different DB servers, routing rules to access a specific database, so that each access to face is not a single server, but the n server, which can reduce the load pressure on a single machine.Data segmentation can also be within the database, to pass through a series of segmentation rules, da

Find the sub-list from the list and the sub-list from the list The usage of the member function is very strange. An element is used to search in the list. If it is found, the elements found and all elements are converted into a new list and returned. If it cannot be found, nil is returned. (set 'aList '(a b c d e f g h)) → (a b c d e f g h)(member 'd aList) → (d e f g h)(member 55 aList)

MySQL Database sub-Library sub-table scheme, once the database is too large, especially when the write is too frequent, very difficult to be supported by a host, we will still face the expansion bottleneck. At this point, we have to find other technical means to solve this bottleneck, that is, this chapter is to introduce the bad data segmentation technology.
