locations needs to be carefully tuned to the extreme.In the core loop, do not use LINQ to object: A LINQ to Object operation that generates at least three lightweight objects: a delegate, an object that implements the IEnumerable interface, and a enumerator that is generated when the collection is traversed.In the core loop, try to minimize the number of cycles. For example: 10 million data and 1 million data do a loop match, the non-optimized loop needs to execute 10 million * 1 million times.

primary key index is used in a query, it also allows quick access to the data.Clustered Index(also calledClustered Index）：InClustered Index, the physical order of the rows in the table is the same as the logical (indexed) Order of the key values. A table can contain only one clustered index. If an index is not a clustered index, the physical order of the rows in the table and the value of the keyLogical Orderdoes not match.AndNonclustered IndexesClustered indexes often provide faster data acc

However, in last August, you can use imagick to generate a CMYK image normally, but today it cannot.After all the test methods and ideas, the solution is as follows. The problem mainly occurs in that the generated QR code is in RGB format and needs to be converted to CMYK, and then the image is synthesized with the CMYK module. First, the previously generated QR code is in PNG format and the bit depth is 8. After analysis, the generated QR

the keyword abstractly can be omitted. The same situation also occurs with the data member, because the data member must be assigned an initial value, and it can no longer be changed, so the keyword final of the declaring data member can also be omitted.The interface in Java is a mechanism for implementing multiple inheritance and is one of the most important aspects of Java design, and each class implemented by an interface must be an abstract method within the replication interface of the cla
