[jira] [Created] (BEAM-13541) Use runtime information to improve CoGroupByKey caching

Sunil Pedapudi created BEAM-13541:
-------------------------------------

             Summary: Use runtime information to improve CoGroupByKey caching
                 Key: BEAM-13541
                 URL: https://issues.apache.org/jira/browse/BEAM-13541
             Project: Beam
          Issue Type: Improvement
          Components: sdk-ideas
            Reporter: Sunil Pedapudi


Currently, CoGroupByKey creates UnionTables that are Flattened. The Flattened output is processed by a GroupByKey to produce a CoGbkResult (via ConstructCoGbkResultFn). 

 

Given the performance of CoGBK is greatly impacted based on the which elements are cached in the (finitely sized) in-memory results, it would be useful if CoGbkResult can use runtime information to prioritize which elements are stored in-memory.
