摘要： Provided are techniques for pipeline optimization based on polymorphic schema knowledge. A hierarchical document to be processed by a pipeline of transformations is received. It is determined whether a next downstream transformation accesses content of each schema node in an associated input schema, wherein the input schema is a polymorphic schema. In response to determining that the next downstream transformation is not accessing the content of each schema node in the associated input schema, data items corresponding to each schema node that the next downstream transformation is not accessing are collected into a single compressed event. The collected items are passed to the next downstream transformation as the single compressed event.

摘要： Provided are techniques for processing data items. A limit on the number of dequeue operations allowed in a current step of processing for a queue-like data structure is set, wherein the number of allowed dequeue operations limit at least one of an amount of CPU resources and an amount of memory resources to be used by an operator. The operator to perform processing is selected and the operator is activated by passing control to the operator, which then dequeues data constrained by the limits set. In response to receiving control back from the operator, the data structure size is examined to determine whether the operator made forward progress in that the operator enqueued or dequeued at least one data item.

摘要： Provided are techniques for optimizing the processing of hierarchical data. A linear processing graph is received, wherein the linear processing graph includes a plurality of operators, wherein each operator in the plurality is connected to at least one other operator by an arc, wherein hierarchical data flows on arcs, wherein the operators read and replace identified subregions within the hierarchical data flowing into the operators on the arcs, and wherein the operators do not modify the hierarchical data outside of these identified subregions. For each operator in the linear processing graph, a minimal set of dependent upstream operators on which that operator depends is found by examining how the identified subregions are created in the linear processing graph through obtaining a set of operators on which that operator depends, by analyzing dependencies carried by a set of vector nodes of the hierarchical data in an input schema of the operator, and, for each of the vector nodes, by analyzing an associated set of scalar nodes, wherein finding the minimum set of operators includes taking into consideration data preservation characteristics of the plurality of operators and taking into consideration structural-order preservation characteristics of the plurality of operators. The linear processing graph is rewritten to create a new graph that expresses dependencies based on the minimal set of dependent upstream operators for each operator.
