This change adds support for disabling datasets, such that specific files are not loaded into memory when running OSRM. This enables users to not pay the memory cost for features they do not intend to use. Initially, there are two options: - ROUTE_GEOMETRY, for disabling overview, steps, annotations and waypoints. - ROUTE_STEPS, for disabling steps only. Attempts to query features for which the datasets are disabled will lead to a DisabledDatasetException being returned.

* Configures an OSRM instance.
|
|
*
|
|
* You can customize the storage OSRM uses for auxiliary files specifying a storage config.
|
|
*
|
|
* You can further set service constraints.
|
|
* These are the maximum number of allowed locations (-1 for unlimited) for the services:
|
|
* - Trip
|
|
* - Route
|
|
* - Table
|
|
* - Match
|
|
* - Nearest
|
|
*
|
|
* In addition, shared memory can be used for datasets loaded with osrm-datastore.
|
|
*
|
|
* You can chose between three algorithms:
|
|
* - Algorithm::CH
|
|
* Contraction Hierarchies, extremely fast queries but slow pre-processing. The default right
|
|
* now.
|
|
* - Algorithm::CoreCH
|
|
* Deprecated, to be removed in v6.0
|
|
* Contraction Hierachies with partial contraction for faster pre-processing but slower
|
|
* queries.
|
|
* - Algorithm::MLD
|
|
* Multi Level Dijkstra, moderately fast in both pre-processing and query.
