Hi James, I'm new to HBase too.
How about this:
with "a range of orderIds", select the first id.
Step1 : set this ID as startRow, then checkout the closest id(Only fetch
one),
Step2:then with this fetched ID, setStartRow(fetchedID-startTimestamp),
setEndRow(fetchedID-endTimestamp),
Step3:
Thank you Ian! Yes, the orderIds are ordered.
I might try timeStamp filter. But it still doesn't provide the early

might be worth having a custom filter to do two partial scans?
Thanks again.

James,
Are your orderIds ordered? You say "a range of orderIds", which implies that
(i.e. they're sequential numbers like 001, 002, etc, not hashes or random
values). If so, then a single scan can hit the rows for multiple contiguous
orderIds (you'd set the start and stop rows based on a prefix

practice to do the scan based on two/multiple partial scans for the
row key.
For example, I have a row key like: orderId-timeStamp-item. The
orderId has nothing to with the timeStamp and i have a requirement to
scan rows f
