> Priority: Major
>
> When we have written 100000 rows in TestTable with 10 preSplits. Then we want
> to test asyncRandomRead, with 10 threads, per thread read 1000 rows. But the
> range of all read keys is in [0, 10000], all in the first region. It may
> cause hotspot problem, and the result is not accurate.
> We can use --size and --rows in randomRead and randomSeekScan at the same
> time, so that the range of reading reaches the entire data set. But
> asyncRandomRead, scanRangeXX, sequentialRead and all the write still have hot
> spot problem.
> This issue add a new option "initRows" to solve this problem.
