I just filed BEAM-104 <https://issues.apache.org/jira/browse/BEAM-104> regarding publishing a capability matrix on the Beam website. We've seeded the spreadsheet linked there ( https://docs.google.com/spreadsheets/d/1OM077lZBARrtUi6g0X0O0PHaIbFKCD6v0djRefQRE1I/edit ) with an initial proposed set of capabilities, as well as descriptions for the model and Cloud Dataflow. If folks for other runners (currently Flink and Spark) could please make sure their columns are filled out as well, it'd be much appreciated. Also let us know if there are capabilities you think we've missed.
Our hope is to get this up and published soon, since we've been getting a lot of questions regarding runner capabilities, portability, etc. -Tyler
