A data synchronization system based on distributed SQL and stream copy
For different real-time require in data synchronization,a data synchronization system is proposed,which is based on distributed SQL and query optimization to achieve data simultaneous distribution and based on log mining and stream copy to achieve asynchronous distribution. The paper gives an application example for data sharing and data synchronization in government sectors. Application results show that the integrated use of synchronous and asynchronous data distribution provides a good solution for data synchronization.
We present here a study for a scheduler which cooperates with the queueing system TORQUE and is tailored to the needs of a HEP-dominated large Grid site with around 10000 jobs slots. Triggered by severe scaling problems of MAUI, a scheduler, referred to as MYSCHED, was developed and put into operation. We discuss conceptional aspects as well as experiences after almost two years of running.
