Abstract
A server system provided according to an aspect of the present disclosure forms physical queries to process a user query received from a client system. Each physical query is thereafter executed in a corresponding concurrent execution entity (e.g., thread) to retrieve a respective data portion from a corresponding data source. A response to the user query is formed based on the data portions. State information corresponding to each execution entity is logged into log storage. According to another aspect, when a query (either physical or user) causes an execution environment to crash, the identifier of such query is added to a prohibited list. When a new query is to be executed, the initiation of execution of the new query is prevented if the identifier of the new query is present in the prohibited list.
