摘要： Various embodiments of systems and methods for a fault tolerance based query execution are described herein. Queries are received from users, the queries including operators. A multi-query optimization is performed on the operators included in the queries to obtain a query plan. A fault tolerance degree is determined for the operators included in the query plan. Based on the fault tolerance degree of the operators, nodes are assigned to the operators included in the query plan. The assigned nodes execute the operators included in the query plan to execute the queries. In one aspect, the nodes simultaneously execute the operators included in the query plan.
