pdg.batchActivation module

The enumeration of batch activation conditions

This enum contains the possible values for when a pdg.BatchWorkItem begins cooking. By default, batches begin when all dependencies for all subitems are ready, however it is possible to generate a batch that cooks when its first subitem or any subitem is ready.

Values

pdg.batchActivation.All

The batch will begin cooking when all subitems have their dependencies satisfied

pdg.batchActivation.Any

The batch will begin cooking when any of the subitems have their dependencies satisfied

pdg.batchActivation.First

The batch will begin cooking when the first subitem has its dependencies satisfied.
