             Summary: Split Beam Python base image into a 'slim' version and 
'regular/extended' version 
                 Key: BEAM-11166
                 URL: https://issues.apache.org/jira/browse/BEAM-11166
             Project: Beam
          Issue Type: Improvement
          Components: sdk-py-core
            Reporter: Valentyn Tymofieiev


Beam container image includes several dependencies that are not essential to 
Beam, but may be commonly used by some users. Some dependencies may be relevant 
only for particular runners. 

Installing dependencies in Beam containers increases image size. For example, 
installing TensorFlow adds ~1G or so of space into the unpacked image.

Some Beam users may be size conscious, and would prefer an image with minimal 
dependencies.

Some Beam users and Beam runner maintainers may prefer an image that includes 
additional dependencies. These extended images may provide better user 
experience in some scenarios, but the overall image would be larger.

We should consider splitting beam image into slim and regular version to 
accommodate these different usage scenarios.
