 ** Task scheduling (1/2)
 *** 
 #+BEAMER: \footnotesize \centering
 https://forge.softwareheritage.org/source/swh-scheduler/
 
 *** What does the Software Heritage scheduler do?
 - Record **recurrent** and **one-shot** jobs in a database
 - Schedules runs of these jobs, records their results
 - Manages retries for transient job failures (remote service unavailable, ...)
 - Manages adaptive intervals for recurrent jobs
 
 ** Task scheduling (2/2)
 
 *** Builds upon trusted Python tools
 - Celery is used as a task queuing middleware, and for its worker management framework
 - Workers send task results through the Celery events mechanism
 
 #+beamer: \pause
 
 *** And makes them more useful to us
 - The database is the single source of truth
 - ~swh.scheduler.celery_backend.runner~ pulls tasks from the database into
   Celery, limiting the RabbitMQ queue depth (allows task prioritization)
 - ~swh.scheduler.celery_backend.listener~ fetches task results from Celery
   events and updates the database
 - Archival of elapsed tasks/runs/logs in elasticsearch to keep the database
   snappy
 
 ** Loading Python packages (1/4)
 
 *** What's a Python package anyway?
 
 - Source distributions (~sdists~, currently tarballs or zips)
 - Binary distributions (~bdists~, which are mostly wheels these days)
 
 As we're interested in source code, Software Heritage looks at ~sdists~ exclusively
 
 #+beamer: \pause
 
 - The current sdist format is unspecified: you probably get a tarball, which
   maybe contains a ~setup.py~ somewhere
 - When building a sdist, distutils generates a machine-readable ~PKG-INFO~ file
   is generated and puts in the tarball
 
 #+beamer: \pause
 
 *** The long wait for PEP 517 ("A build-system independent format for source trees")
 
 - One uniform transport format: a gzipped tarball with one toplevel directory
 - Machine parsable data about the project by default (~pyproject.toml~)
 Hopefully soon in your nearest Cheese Shop (go help the folks in PyPA!)

-** Task scheduling (1/2)
-*** 
-#+BEAMER: \footnotesize \centering
-https://forge.softwareheritage.org/source/swh-scheduler/
-
-*** What does the Software Heritage scheduler do?
-- Record **recurrent** and **one-shot** jobs in a database
-- Schedules runs of these jobs, records their results
-- Manages retries for transient job failures (remote service unavailable, ...)
-- Manages adaptive intervals for recurrent jobs
-
-** Task scheduling (2/2)
-
-*** Builds upon trusted Python tools
-- Celery is used as a task queuing middleware, and for its worker management framework
-- Workers send task results through the Celery events mechanism
-
-#+beamer: \pause
-
-*** And makes them more useful to us
-- The database is the single source of truth
-- ~swh.scheduler.celery_backend.runner~ pulls tasks from the database into
-  Celery, limiting the RabbitMQ queue depth (allows task prioritization)
-- ~swh.scheduler.celery_backend.listener~ fetches task results from Celery
-  events and updates the database
-- Archival of elapsed tasks/runs/logs in elasticsearch to keep the database
-  snappy

-** Loading Python packages (1/4)
-
-*** What's a Python package anyway?
-
-- Source distributions (~sdists~, currently tarballs or zips)
-- Binary distributions (~bdists~, which are mostly wheels these days)
-
-As we're interested in source code, Software Heritage looks at ~sdists~ exclusively
-
-#+beamer: \pause
-
-- The current sdist format is unspecified: you probably get a tarball, which
-  maybe contains a ~setup.py~ somewhere
-- When building a sdist, distutils generates a machine-readable ~PKG-INFO~ file
-  is generated and puts in the tarball
-
-#+beamer: \pause
-
-*** The long wait for PEP 517 ("A build-system independent format for source trees")
-
-- One uniform transport format: a gzipped tarball with one toplevel directory
-- Machine parsable data about the project by default (~pyproject.toml~)
-Hopefully soon in your nearest Cheese Shop (go help the folks in PyPA!)
