 Luigi tasks
 ===========
 
 This package contains `Luigi <https://luigi.readthedocs.io/>`_ tasks.
 These come in two kinds:
 
 * in :mod:`swh.graph.luigi.compressed_graph`: an alternative to the 'swh graph compress'
   CLI that can be composed with other tasks, such as swh-dataset's
 * in other submodules: tasks driving the creation of specific datasets that are
   generated using the compressed graph
 
 
 The overall directory structure is::
 
     base_dir/
         <date>[_<flavor>]/
             edges/
                 ...
             orc/
                 ...
             compressed/
                 graph.graph
                 graph.mph
                 ...
                 meta/
                     export.json
                     compression.json
             datasets/
                 contribution_graph.csv.zst
             topology/
                 topological_order_dfs.csv.zst
 
 And optionally::
 
     sensitive_base_dir/
         <date>[_<flavor>]/
             persons_sha256_to_name.csv.zst
             datasets/
                 contribution_graph.deanonymized.csv.zst
