There is an issue about it in Azure DevOps GitHub and Microsoft answered:
Hey everyone - I'm from the Azure Artifacts team and we built the
Pipeline Artifacts feature that you've discovered in Azure Pipelines.
I'll address the most important comment around documentation - we've
got a whole new page coming out around Artifacts in Azure Pipelines
which lists out each artifact type that we support and what they are
for along with links to specific documentation. We think that should
answer most of your questions.
Because that is still being edited before we publish it I thought I
would give you the 30,000 foot view on the difference between Pipeline
Artifacts and Build Artifacts and also mention how Pipeline Artifacts
relate to Universal Packages.
Build Artifacts (published via the Publish Build Artifacts task) have
been in Azure DevOps for a long time and are the built-in artifact
storage mechanism for Azure Pipelines. Most builds that store
non-package artifacts today would likely use this task. The task can
push the content up to the server/cloud but can also copy the files to
a local file share.
Pipeline Artifacts (published using the Publish Pipeline Artifact task
are intended as the replacement for Build Artifacts. They are in
preview right now and there are a few more things we need to do to
reach parity. The benefit of Pipeline Artifacts is that they can
dramatically reduce the time it takes to upload and download large
artifacts. We do this be first checking whether the content that is
being uploaded exists in the service. We do this not just at the
per-file level but also at the sub-file level (in up to 128K chunks).
It can lead to really dramatic performance improvements.
Universal Packages - also in preview use the same storage/transfer
technology as Pipeline Artifacts. You would use Universal Packages
when you want to create an artifact with a life time independent of
the pipeline that created it. You can download Pipeline Artifacts
after a pipeline has completed via the artifacts UX - but if you want
something that really exists independent of pipeline you would go for
Universal Packages. There should be no performance difference between
the two.
Hopefully this helps. Feel free to ask any more questions and I'll
follow-up with answers.
