> Currently, the default value of taskmanager.network.sort-shuffle.min-buffers
> is 64, which is pretty small. As suggested, we'd like to increase the default
> value of taskmanager.network.sort-shuffle.min-buffers. By increasing the
> default taskmanager.network.sort-shuffle.min-buffers, the corner case of very
> small in-memory sort-buffer and write-buffer can be avoid, which is better
> for performance.
