Abstract: A system and method of isolated testing platform for cloud database production queries. The method includes providing an execution platform including a production deployment to receive a first group of queries from a first group of user devices. The production deployment includes a local data storage to store a first dataset associated with the first group of user devices and an execution node to process the first group of queries based on a first version of an application and based on the user data. The method includes receiving a request to test a second version of the application based on the first version of the application. The method includes deploying a ghost deployment onto the execution platform. The method includes replaying the first group of queries on the ghost deployment using copies of the first version of the application and the second version of the application.
