Use the `tls=1` and the set the the `tlscert` and `tlskey` query
string params. The cert and key files must be on the tile38
server and the Nats server must be started using the same files.
nats://54.12.34.121:4222/fleet?tls=1&tlscert=cert.crt&tlskey=cert.key
Unless the credpath query param is provided, the SQS credidentails
will be automatically chosen from one of the following:
- ~/.aws/credidentials
- Environment variables
- EC2 Role
The big change is that the GeoJSON package has been completely
rewritten to fix a few of geometry calculation bugs, increase
performance, and to better follow the GeoJSON spec RFC 7946.
GeoJSON updates
- A LineString now requires at least two points.
- All json members, even foreign, now persist with the object.
- The bbox member persists too but is no longer used for geometry
calculations. This is change in behavior. Previously Tile38 would
treat the bbox as the object's physical rectangle.
- Corrections to geometry intersects and within calculations.
Faster spatial queries
- The performance of Point-in-polygon and object intersect operations
are greatly improved for complex polygons and line strings. It went
from O(n) to roughly O(log n).
- The same for all collection types with many children, including
FeatureCollection, GeometryCollection, MultiPoint, MultiLineString,
and MultiPolygon.
Codebase changes
- The pkg directory has been renamed to internal
- The GeoJSON internal package has been moved to a seperate repo at
https://github.com/tidwall/geojson. It's now vendored.
Please look out for higher memory usage for datasets using complex
shapes. A complex shape is one that has 64 or more points. For these
shapes it's expected that there will be increase of least 54 bytes per
point.
