It's a simple struct with (link_id, from_id, to_id), which we store in a central BAT. One common operation is, of course, finding the neighbors of a given object, and we would like to be able to do that efficiently, without a full table scan every time. We can build internal data structures every time we do a select on the BAT, but it would be more efficient to have a persistent data structure that we can somehow re-use. We've read the old GIS paper, and our needs are pretty similar to those. Is that code still active, somewhere? Could we take a look at it? Is there any other place where yo do similar things, such as having BATs of a new datatype and searching/joining them efficiently? Too many questions, I know ;-) Thanks! -- Agustin ------------------------------------------------------------------------- Take Surveys. Earn Cash.
