[GitHub] [beam] scwhittle opened a new issue, #22438: [Bug]: Dataflow runner can become stuck with batched state fetches if coder exceptions are caught

scwhittle opened a new issue, #22438:
URL: https://github.com/apache/beam/issues/22438

   ### What happened?
   
   WindmillStateReader consumes batched read requests for a key.  If there are exceptions processing some of the values/tags etc, an exception is thrown but other futures may be left unfulfilled. If the exception is caught by the user and other values are then read, they may block forever on the future.
   
   A fix would be to process the remainder of the response before throwing the exception further, and to ensure that all futures that were not completed by the response are completed with an exception.
   
   ### Issue Priority
   
   Priority: 2
   
   ### Issue Component
   
   Component: runner-dataflow
