Hi all,
I built a tree in orientdb with a high amount of nodes and edges in bottom
up direction. I would like to receive all leaves of that tree (each leaf
has the @class LEAF) which match a certain range condition (e.g. val > 150
and val < 300):
Example:
o
/ \
o o
/ / \
o o o
210 120 /\
270 180
Result: 210, 180, 270
What I tried so far is to use the following query:
SELECT FROM(TRAVERSE IN() FROM #123:123) WHERE value > 150 and value < 300
This is working well with a few elements but the performance drops with
increasing amount of leafs. So my questions are:
1. Is this the most efficient way to do this in OrientDB, especially if
I have let's say 300000 leaves under each node ?
2. I know from the documentation, that using an index can help to
improve the performance on range queries, but would the index be used in
this case? My first assumption is no because orient is first traversing and
then filtering the the traversed elements isn't it?
Thanks and Regards
Jon
