Fabric Runtime - Python Library Origin

Hi sjmartin 

The official documentation does not specify which repository the built-in libraries are installed from, but I believe they are sourced from secure and reliable repositories because Microsoft takes the security of its software products and services seriously. Since the Fabric runtime includes not only Python modules but also Java, Scala, and R libraries, they are probably not sourced from a single repository but from several repositories. You don’t need to worry about the security of the library sources.

To view which built-in libraries are installed by default, you can try creating a new environment, switching to the runtime you want to explore from the runtime dropdown at the top, and going to the Built-in libraries page. If you switch to the Public libraries page, you can install additional libraries from PyPI or Conda repositories.

For more detailed information about every update within Fabric Runtime 1.3, please go to the following Github page: synapse-spark-runtime/Fabric/Runtime 1.3 (Spark 3.5) · GitHub
