MyISAM types do not support advanced processing such as transaction processing, and InnoDB type support.Tables of the MyISAM type emphasize performance, which is performed more quickly than the InnoDB type, but does not provide transactional support.InnoDB provides transactional support and advanced database features such as foreign keys.This makes it possible to use different storage types depending on the data table.In addition, MyISAM types of binary data files can be migrated in different op

WiredtigerMongoDB itself owns the MMAPv1 engine, and in version 3.0 It added the previously acquired Wiredtiger storage engine technology.through Wiredtiger , MongoDB 3.0 implements the Document-level concurrency control (Concurrency Control), thus greatly improving the write load under large concurrency . Users can choose the compression ratio of their own storage data, MongoDB 3.0 provides the maximum com

The MyISAM type does not support advanced processing such as transaction processing, while the InnoDB type supports. This article will explain the differences between engineinnodb and enginemyisam in mysql. If you do not know how to learn, I hope it will be helpful for you. When you first use MySQLAdministrator to create a database, the default table type is InnoDB, so you don't care. Later, Ac The MyISAM type does not support advanced processing such as transaction processing, while the InnoDB

MySQL FEDERATED engine and mysqlfederated EngineThe FEDERATED storage engine accesses the data in the table of the remote database, rather than the local table. This feature facilitates some development applications. You can directly create a federated table locally to connect to the remote data table. After configuration, the data in the local table can be directly synchronized with the remote data table.

People around us and companies around us are all crazy. It seems that the bet is all over this. I am wondering that a few years ago, the Institute has thoroughly studied search algorithms. It seems that they have not been commercialized until now, so patent technology quickly depreciates. I used to perform full-text retrieval of multimedia materials. Since all of them are reading, I will also review the old knowledge.Article. I have to lament that on the Internet, it is difficult to see promis
