> We found that when the read load on a specific RS is high, the write
> throughput also get impacted dramatically, and even cause write data loss
> sometimes. We want to prioritize the write by putting them in a separate
> queue from the read request, so that slower read will not make fast write
> wait nu-necessarily long.
