table data is consistent with the source table data. Because MySQL restricts only one trigger of the same type, it requires a primary key or a unique index on the table to check for triggers on the source table before running, to ensure efficiency and ease of deletion and update, and to shard the source table data. ##

Batch processing is a non-interactive way to run mysql programs. like the commands you use in mysql, you will still use these commands. To implement batch processing, you need to redirect a file to the mysql program. First, we need a text file containing the same text as the command we entered in mysql. For example, we

In XEN/KVM virtualization, CPU, memory, and network I/O are generally more efficient in virtualization, and disk I/O virtualization is inefficient, so the disk can be a bottleneck. In general, the database has high disk I/O requirements, and can measure the performance of running MySQL, Oracle, and other database services on the client (although I know that it is also more efficient to run the database server in the client). This article does not desc

stable: the same SELECT query statement under the conditions of millions, tens of millions, and hundreds of millions of records is faster than ordinary MySQL storage engines such as MyISAM and InnoDB ~ 60 times. Efficient query mainly relies on the specially designed storage structure to optimize the query. However, the optimization effect depends on the database structure and query statement design.
