Set/get metadata at locations in addition to name

[vvavepacket]

Hi,

GeoRedis feature currently utilizes 3 properties: latitude, longitude, and name. When adding a location, is it possible to add additional key value pairs aside from name itself? Let us say we are adding name, address, etc. Is it possible? If not, what are best workaround / practices?

@vvavepacket Yeah, best bet is to have another hash store based on names. Redis stores everything as strings or numbers, but you can use hmset/hmget at least have some metadata. ie. client.hmset("mylocationname", { a: 1, b: 2, c: 'xxx' })

Redis isn't super great for relational queries or storing complex objects at a key. Though, I actually think it could be a nice convenience to be able to store simple metadata for a location. It would be probably be limited to a shallow object of either strings and numbers.

I would like to leave this open as a feature request.

Ideally the API would look like:

geo.addLocation('locationname', position, {
    address: '265 Homer Lane',
    city: 'Lalaland, CA',
    rank: 3
})

geo.location('locationname', function(err, location) {
    console.log('Location information', location.data);
})

But, I'd really have to consider how to implement this without drastically reducing performance. Particularly for the getting of location metadata. I think the retrival of metadata may have to be an option, like:

geo.location('locationname', { withData: true }, function(err, location) {
    console.log('Location information', location.data);
})

That way we could gate whether or not to make an additional request for data.

maybe instead of:

geo.addLocation('locationname', position, { 
    address: '265 Homer Lane',
    city: 'Lalaland, CA',
    rank: 3
})

we can work with:

geo.addLocation('locationname', {
    latitude: 43.6667, 
    longitude: -79.4167,
    address: '265 Homer Lane',
    city: 'Lalaland, CA',
    rank: 3
})

latitude -> required longitude -> required
