Approaches to storing geospatial data in Redis

Question

I\'ve got a MySQL table consisting of roughly 1 million latitudes and longitudes with a primary key value for each row.

I\'d like to migrate this table into Redis either

Answer 1

Another project you maybe want to have a look into is Tile38.

Tile38 is a geolocation data store, spatial index, and realtime geofence. It supports a variety of object types including lat/lon points, bounding boxes, XYZ tiles, Geohashes, and GeoJSON.

Querying in particular seems really nice to use. For example you can set fences which trigger webhooks.

I don't know about migrating data though.

Answer 2

Yes, it has already been done (using geohashing ...)

You can check for instance the data structure behind the Geodis package (from Dvir Volk and friends):

There were some discussions about it on the Redis mailing-list:
