Abstract

In some implementations, there is provided a method that includes detecting in a query plan a pipeline that includes a last restart query operator that can cause a retry of the query plan during execution of the query plan; configuring the pipeline to execute the pipeline using an open call configuration, configuring at least one subsequent pipeline to execute in a fetch call configuration; executing the query plan including the pipeline in the open call configuration; sending, by the send operator, a message indicating the last restart query operator cannot cause a retry of the execution of the query plan; and causing execution of at least one operator in the subsequent pipeline to execute in the fetch call configuration, in which result streaming of partial results is allowed for the at least one operator.
