      Work Description: tweise commented on issue #6208: [WIP] [BEAM-2930] Side 
input support for Flink portable streaming.
URL: https://github.com/apache/beam/pull/6208#issuecomment-413916534
 
 
   What is supposed to happen when the windowing strategy allows early/repeated 
firing? Won't that lead to indeterministic behavior? 
   
   If repeated firing is possible, then my current approach of just 
accumulating records into an Iterable won't work. 
   
   With the non portable runner, views are materialized via combine. While that 
would ensure that the Iterable is constructed correctly, repeated firing would 
still lead to indeterministic results. Anyone with better understanding of the 
old Flink runner can offer any insight here?
