Adaptive geographical data caching based on a route pattern

A method comprising:

• loading, at a computing node, an assigned portion of map data for use, by the computing node, in servicing a received geographic routing request;
• accessing, at the computing node, historical geographic route data describing one or more geographic routes generated in the past;
• identifying, at the computing node, additional map data based on the accessed historical geographic route data, the additional map data being different from the assigned portion of map data;
• and
• accessing, at the computing node, the additional map data from a data source external to the computing node.

A non-transitory computer storage medium comprising instructions that, when executed by one or more hardware processors of a computing node, cause the computing node to perform operations comprising:

• loading an assigned portion of map data for use, by the computing node, in servicing a received geographic routing request;
• accessing, from a data source external to the computing node, additional map data based on the assigned portion of the map data;
• and
• storing the additional map data to a cache at the computing node.
