> 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.
