> Skip between timestamps to avoid the unnecessary read for all the blocks which come in
between.
> For example:
> If we have timestamps from 1 to 1000 for a particular row, family, qualifier and we want
to read only timestamps 990 and 10, then we should be able to read 990 and then jump to 10
instead of doing a sequential read including everything in between.
