Is pgr_createTopology deterministic in how it numbers nodes in a built<br>
topology?<br>
</blockquote>

Stephen,<br>
<br>
What do you mean by this?<br>
<br>
If you build a topology on the same edge table twice, do we guarantee that the nodes numbers will be identical?<br>
<br>
I think the answer is NO, on line:303 of src/common/sql/pgrouting_<u></u>topology.sql there is no "order by" clause. This would need to be added to make it deterministic because relational set theory does not guarantee order of records in a query without explicitly including and "order by" clause.<br>
<br>
Write a bug if you think this is needed and state why.<br>
<br>
Thanks,<br>
-Steve<br>
