Processing a data flow graph of a hybrid flow can include a data structure to store metadata for each of a plurality of nodes of a data flow graph of a hybrid flow, processing the data flow graph of the hybrid flow, and defining metadata in the data structure for a particular node affected during processing of the data flow graph of the hybrid flow.

Processing a data flow graph of a hybrid flow

Converting a hybrid flow can include combining each of a plurality of task nodes with a plurality of corresponding operators of the hybrid flow and converting the combined plurality of task nodes and the plurality of corresponding operators of the hybrid flow to a data flow graph using a code template.

Converting a hybrid flow

Described herein are techniques for processing analytic flows. A physical flow can be parsed into multiple elements. A logical representation can be generated based on the physical flow using a dictionary. An engine-specific logical representation or second physical flow can then be generated based on the logical representation using the dictionary.

Generating a logical representation from a physical flow

A technique of optimizing analytic flows includes sampling source data using a sampling method, executing a flow over the sampled data, obtaining runtime statistics from the executed flow, and combining runtime statistics with historical statistics.
