    I don't think we want to support too larger interval for this. Having very high value
means prolonging the memory check which is bad (flush often as opposed to don't flush and
    1 to 10000 may be good range. Also please make a note in the description that keeping
too low value is for testing only and can cause too early flushes in some cases and generate
sub-optimal orc files.
