Description

In order to avoid writing produced results multiple times for multiple consumers and in order to speed up batch recoveries, we should make the blocking result partitions to be consumable multiple times. At the moment a blocking result partition will be released once the consumers has processed all data. Instead the result partition should be released once the next blocking result has been produced and all consumers of a blocking result partition have terminated. Moreover, blocking results should not hold on slot resources like network buffers or memory as it is currently the case with SpillableSubpartitions.
