aerospike
Starting with version 3.7.0, the Aerospike server supports storing GeoJSON data. A Geo2DSphere index can be built on a bin which contains GeoJSON data, enabling queries for the points contained within given shapes using ~aerospike.predicates.geo_within_geojson_region
and ~aerospike.predicates.geo_within_radius
, and for the regions which contain a point using ~aerospike.predicates.geo_contains_geojson_point
and ~aerospike.predicates.geo_contains_point
.
On the client side, wrapping geospatial data in an instance of the aerospike.GeoJSON
class enables serialization of the data into the correct type during write operation, such as ~aerospike.Client.put
. On reading a record from the server, bins with geospatial data it will be deserialized into a ~aerospike.GeoJSON
instance.

# Store the record.

client.close()
Optionally initializes an object with a GeoJSON str
or a dict
of geospatial data.
wrap(geo_data)
Sets the geospatial data of the ~aerospike.GeoJSON
wrapper class.
- param dict geo_data
a
dict
representing the geospatial data.
unwrap() -> dict of geospatial data
Gets the geospatial data contained in the ~aerospike.GeoJSON
class.
- return
a
dict
representing the geospatial data.
loads(raw_geo)
Sets the geospatial data of the ~aerospike.GeoJSON
wrapper class from a GeoJSON string.
- param str raw_geo
a GeoJSON string representation.
dumps() -> a GeoJSON string
Gets the geospatial data contained in the ~aerospike.GeoJSON
class as a GeoJSON string.
- return
a GeoJSON
str
representing the geospatial data.
