深度4之后OrientDB缓慢遍历

Question

OrientDB is slow after the traversal is greater than depth 3. (depth 3 took 4 seconds, depth 4 took 11, depth 5 took 37 seconds)

My query is: TRAVERSE * FROM (select from products where pid = '73') while $depth<=5

Products extends from V and I have an index type UNIQUE (field pid) with engine SBTree. When I try with depth 1 until 3 works fine. I compared with Neo4j and took 3 seconds in depth 5 with the same data. I am working with OrientDB 2.1.5 Please help me to improve this. Thanks.

Answer 1

Try using:

TRAVERSE * FROM (select from products where pid = '73') maxdepth 5

How many records do you have at 4th and 5th level?
