Hello, I have a question similar to #3. Is there any add-on or library on top of Hbase handling spatial algorithms? For example couchdb has something called GeoCouch. Thanks!

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! -Mike
