[jira] [Created] (KAFKA-12649) Expose cache resizer for dynamic memory allocation

A. Sophie Blee-Goldman created KAFKA-12649:
----------------------------------------------

             Summary: Expose cache resizer for dynamic memory allocation
                 Key: KAFKA-12649
                 URL: https://issues.apache.org/jira/browse/KAFKA-12649
             Project: Kafka
          Issue Type: New Feature
          Components: streams
            Reporter: A. Sophie Blee-Goldman


When we added the add/removeStreamThread() APIs to Streams, we implemented a cache resizer to adjust the allocated cache memory per thread accordingly. We could expose that to users as a public API to let them dynamically increase/decrease the amount of memory for the Streams cache (ie cache.max.bytes.buffering).
