Once you have a session, you can use it to execute the mapping statement, commit or rollback the connection, and finally, when you no longer need it, you can close the session. After using mybatis-spring, you no longer need to use sqlsessionfactory directly, because your bean can be injected through a thread-safe sqlsession, automatically commit

Device Mapper is a kernel-based framework that enhances many advanced volume management technologies on Linux. Docker's Devicemapper Drive leverages the framework's hyper-provisioning and snapshot capabilities for mirroring and container management. To differentiate, this article uses device Mapper to refer to the framework in the drive, while Devicemapper refers to the storage driver for Docker.　　Note : Co

Jérôme Petazzoni (Docker evangelist) Translator: Mark Shao (senior engineer, EMC China) If you use Docker on CentOS, Rehl, Fedor, or other Linux distributions that do not have AUFS support by default, you may need to use Device Mapper's storage plug-in. By setting this plugin as the default, it will store all your containers in a short 100G file and limit the maximum of 10GB per container. This article will show you how to break this limit and move the storage of the container to a specifi

Using the Mapper interface, without writing the interface implementation class, directly complete the database operation, simple and convenient. In order to help everyone to better learn Mapper interface, small series summed up some knowledge about the Mapper interface, hope to help people in need.

This article mainly introduces the PHP object-oriented domain model + data Mapper instance graphics and text detailed, interested in the friend's reference, I hope to help you. The code and annotations are as follows: The three data table structures related to the domain model are venue (venue), space (spatial), event (events), respectively. CREATE TABLE ' venue ' ( ' id ' int (one) not null auto_increment, ' name ' text, primary key (' ID ')

The advantage of the MapReduce framework is the ability to run mapper and reducer tasks in parallel in the cluster, how to determine the number of mapper and reducer, or how to programmatically control the number of mapper and reducer that the job initiates? In the mapper and reducer of the Hadoop-2.4.1 study, the numb
