Calculating durations is unavoidable due to tie-breaking minimums, but we can avoid accumulating distances if they're not requested. 2018-10-30 15:41:06 -07:00

Replace dynamic distance calculation for table plugin with pre-calculated distances on shortcuts, avoiding unpacking cost.
Adds approx 10% to total data size.  Speeds up large table requests by 2 orders of magnitude.

bf2b45120a Use ArrayStorage for boundary nodes to optimize MLD
For the MLD algorithm we can partition the NodeID range into boundary
and non-boundary nodes. Since there are only we boundary nodes we can
use the ArrayStorage for those yielding much faster query times.

8114104a43 Rename namespace partition to partitioner
Rename module partition to partitioner.
This cultivates naming used in existing modules like extractor,
customizer, etc. - noun vs verb (word partition is both though).

f2333eb31a Break tie for equal weights but different durations
There is no possibility until multiple-weights are implemented
to break tie in the contraction and the direct shortest path plugin
as duration is not computed during contraction.

This must be fixed after multiple-weights implementation
by using `std::tie(weight, duration)` pairs everywhere.
