-----------------------------------
Summary: Distribute the data read buffers more fairly among result
partitions for sort-shuffle
Key: FLINK-25960
URL: https://issues.apache.org/jira/browse/FLINK-25960
Project: Flink
Issue Type: Sub-task
Components: Runtime / Network
Reporter: Yingjie Cao
Fix For: 1.15.0
Currently, the data read buffers for sort-shuffle are allocated in a random way
and some result partitions may occupy too many buffers which leads to the
starvation of other result partitions. This ticket aims to improve the scenario
by not reading data for those result partitions which already occupy more than
the average number of read buffers per result partition.
