Hongbing Wang updated HDDS-10846:
---------------------------------
Description:
Current code:
{code:java}
public TaskType decideReadWriteOrListTask() {
int tmp = ThreadLocalRandom.current().nextInt(1, 101);
if (tmp <= percentageRead) {
return TaskType.READ_TASK;
} else if (tmp <= percentageRead + percentageList) {
return TaskType.LIST_TASK;
} else {
return TaskType.WRITE_TASK;
}
} {code}
using random numbers to divides tasks is not accurate, especially when the
number of threads is small.
> ozone freon ockrw accurately divides the ratio of tasks when mixed operations
