2024-05: version 0.1-alpha

[jfathi]

Initial release - first major upgrades since 2022:

Conditional Edges: DAGs can now continue execution along a node-path in case of a parent node's failure! Edge conditions are documented as in the enum webber.Condition, as OnSuccess, OnFailure, or AnyCase. Default edge condition is OnSuccess.

Retry and Skip: Nodes can now be re-executed multiple times in case of failure, or skipped over entirely. Currently, skips are registered as a successful node execution.

Trace Exceptions: Trace printouts disabled by default, can be enabled at DAG execution time: DAG.execute(print_exc=True)

Other Improvements:

• Use UUID4 to limit repeating GUIDs.
• Complex xcoms deprecated in favor of Promise model.

Known bugs and Gaps:

• STDOUT logging is not guaranteed to correlate to correct node at 3+ concurrent operations.
• Visualizations for Jupyter Notebooks are largely unsupported at this time.

Under Development:

• Additional documentation, visualization improvements forthcoming in v0.1.1
• Critical Node Paths: DAGs can be reduced to a set of specified nodes and their dependencies.

Project Backlog:

• Support for Jupyter Notebook visualizations
• Get/Update Functions for Nodes and Edges
• Edge and Node filtering with Lambda Functions (e.g.: lambda e: e.Condition == condition.OnSuccess).
