Hi,
A fellow co-worker was asking some questions and while I thought I might know
the answer I wasn't 100% sure that I was right.
So I figure its better to be safe than sorry, and forward the questions out to
the list because I know that there are a couple of wonks who know this stuff
off the top of their head. :-)(Also its a great way to get the correct answer
documented so others can hit Google/Yahoo/<insert your favorite search engine>
and find a response.)
Here are the questions:
1.
Where is filtering happening?
Is it on the client or at the read time?
2.
In the result
scanner, when are records delivered to the client? When I do next? In
other words what is the penalty for having scan wider than the actual data that
I need
3.
Where can I find the
example of custom WritableByteArrayComparable and Comparator? How do I decide
which one to overwrite?
IMHO I think #3 is a good thing to get documented.
Thinking of a spatial query where you want to find all of the data from points
within a given volume... It would make life easier.
TIA!
