Thomas Weise commented on BEAM-980:
-----------------------------------

The runner should probably have an option to specify a configuration file so 
that users can tune the execution attributes similar to what they can do when 
launching through the Apex CLI.

> The Beam pipeline is translated to an Apex DAG of operators that have names 
> that are derived from the transforms. In case of composite transforms those 
> look like path names. Apex lets the user configure things like memory, 
> vcores, parallelism through properties/attributes that reference the operator 
> names. The configuration approach needs to be documented and supplemented 
> with an example.
