.. _luigi-features-label: ``luigi`` Features ================== ``luigi`` already has many nice and helpful features. All of them can be used with ``b2luigi`` as well. In the following is a collection of the most important features. Please note, that the following list is not exhaustive; check the `luigi documentation `_ for more information. The Central Scheduler --------------------- When the number of tasks grows, it is sometimes hard to keep track of all of them (despite the summary in the end). For this, ``luigi`` (the parent project of ``b2luigi``) brings a nice visualization and scheduling tool called `the central scheduler `_. If you are submitting your jobs from a remote machine, you can forward the schedulers port to your local machine via ssh. In the ``examples/scheduler`` directory of ``b2luigi``, you can find an example script (``query_scheduler.py``) that demonstrates how to query the central scheduler and retrieve the status of tasks. This example provides a lightweight alternative for monitoring the status of your workflow without relying on the web interface. Parameters ---------- ``luigi`` already has various Parameter types to pass to your tasks, like :obj:`ListParameter`, :obj:`IntParameter`, :obj:`DateParameter` and many more. Check the `luigi parameter documentation `_ for more information. Logging ------- ``luigi`` has some `logging features `_ built in. Even more settings ------------------ Many aspects of ``luigi``'s scheduling mechanism can be controlled via the `luigi configuration `_. Please be aware that these settings are a separate configuration from the settings in ``b2luigi``. Yes, this is very confusing, but historically grown. At some point in the future, this might change. Resource Management ------------------- Using the central scheduler, ``luigi`` can do some simple `resource management `_. Just set the available resources in the `luigi.cfg` and set the amount used as a task property.
