[pgrouting-users] scalability of driving_distance

Hi all,

I am interested in two things:

1) what is the scalability of this function, when do I get a out of memory? (I tested until 11,000,000 of edges and it is still working fine.)

2) what kind of data structure is used to store the edges? Is it an adjacency list or adjacency matrix. I suppose it is a main memory data structure

thanks for your answer

Hi Markus,

1. Always worked, never failed :slight_smile:
Seriously, we never tested it for such things. Perhaps we didn't met a
data set big enough.

2. Adjacency list.

Anton.

I will try to find out the limits. I let you know, at what size it throw such exception
