1. A method comprising:
determining semantic objects to be stored in a shard;
generating a shard file to be stored in a file storage system, wherein the shard file includes data of the semantic objects for the shard;
generating shard metadata for the shard, wherein the shard metadata includes:
(1) a unique string value representing a name of the shard, the unique string value comprising a non-unique string value representing a subtype of the shard and a sequence number; and
(2) floating point values defining a polygonal shape indicative of an area that is covered by the semantic objects of the shard;
generating a shard metadata file having the shard metadata for the shard to be stored in the file storage system; and
delivering the shard file to one or more clients using the shard metadata file, wherein the one or more clients include one or more of: an autonomous vehicle, a vehicle, and a computer environment, and wherein delivering the shard file comprises:
receiving filter data that is requested by the one or more clients, wherein the filter data is indicative of map data and a route planned for traversal by the one or more clients and the filter data includes bounding box information corresponding to the requested map data;
temporarily enlarging the polygonal shape of the shard by a configurable padding zone based on a distance of objects that may affect autonomous vehicle behavior; and
correlating the filter data against the shard metadata file having the enlarged polygonal shape to determine whether the shard file is relevant to the filter data.
