Scalable Transaction Management on Cloud Data Management Systems

Abstract

Cloud computing is a model for enabling convenient, on -demand network access to shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort . As the problem of building scalable trans-action management mechanisms for multi-row transactions on key-value storage systems . For that purpose we develop scalable techniques for transaction management by using the snapshot isolation (SI) model. This SI model can give non-serializable transaction executions, we investigate two conflict detection techniques for ensuring serializability under SI. As getting importance of scalability, we investigate system models and mechanisms in which the transaction management functions are decoupled from the storage system and integrated with the application-level processes. We present two system models and demonstrate their scalability under the scale-out paradigm of Cloud com-putting platforms. In the first system model, all transaction management functions are executed in a fully decentralized manner by the application processes. The second model is based on a hybrid approach in which the conflict detection techniques are implemented by a dedicated service.
