A system enables an arbitrary number of items to be indexed in a geographic region that provides a predictable query response time across a sharded database. Items indexed to the geographic region are stored on a single shard and additional items are added to that shard as long as an overflow condition indicative of undesirable query response times is not met. If the overflow condition is met the system expands the storage of items indexed to the geographic region to one or more additional shards in order to maintain predictable query response times. The system may maintain a shard count representing the total number of shards being used to store items corresponding to a geographic region, which can be used to query one or more relevant shards. The system may apply deterministic hashing in order to evenly distribute shards across database nodes of the sharded database.

An augmented reality system generates computer-mediated reality on a client device. The client device has sensors including a camera configured to capture image data of an environment. The augmented reality system generates a first 3D map of the environment around the client device based on captured image data. The server receives image data captured from a second client device in the environment and generates a second 3D map of the environment. The server links the first and second 3D together in a singular 3D map. The singular 3D map may be a graphical representation of the real world using nodes that represent 3D maps generated by image data captured at client devices and edges that represent transformations between the nodes.
