Drone introduction
Drone is a new generation of CI/CD tools, based on Pipeline+docker mode, can be very flexible to support many business scenarios, currently, done up to 0.8.6, on GitHub, has scored 15K Takaboshi star.
Drone and Gitlab, you can set the. drone.yml file in your project to customize the various processes you need to perform, such as code fetching,
possibly generate a large number of read I/O operations, which are resource-intensive operations. If you can reduce the Redo and Undo writes of Undo in these processes, it can obviously greatly improve database performance and reduce resource consumption and usage.
Oracle introduced the In Memory Undo (IMU) technology In the database starting from Oracle10g. With this technology, the database will be In the Shared Memory (Shared Pool) the independen
