Selective checkpointing of links in a data flow based on a set of predefined criteria
Techniques are disclosed for qualified checkpointing of a data flow model having data flow operators and links connecting the data flow operators. A link of the data flow model is selected based on a set of checkpoint criteria. A checkpoint is generated for the selected link. The checkpoint is selected from different checkpoint types. The generated checkpoint is assigned to the selected link. The data flow model, having at least one link with no assigned checkpoint, is executed.
