[jira] [Created] (BEAM-9964) Setting workerCacheMb to make its way to the WindmillStateCache Constructor

             Summary: Setting workerCacheMb to make its way to the WindmillStateCache Constructor
                 Key: BEAM-9964
                 URL: https://issues.apache.org/jira/browse/BEAM-9964
             Project: Beam
          Issue Type: Improvement
          Components: runner-dataflow
            Reporter: Omar Ismail


Setting --workerCacheMB seems to affect batch pipelines only. For Streaming, the cache seems to be hardcoded to 100Mb [1]. If possible, I would like to make it allowable to change the cache value in Streaming when setting --workerCacheMB.

I've never made changes to the Beam SDK, so I am super excited to work on this!
