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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
