geo_spatial_index

Category: Geospatial
Wire type: geo_spatial_index
Construction: CREATE

Geospatial types use latitude/longitude coordinates and spatial predicates.

Create a value

Use the top-level CREATE command to initialize this structured value. The example shows its construction options.

amaquet-cli -uri amaquet://127.0.0.1:13378 CREATE '{"key":"example:geo_spatial_index","type":"geo_spatial_index","options":{}}'

Construction options

Example CREATE options: {}. Omitted fields use server defaults.

Supported operations

ADD, REMOVE, RADIUS, BOX, POLYGON.

See the complete operation contract for exact arguments, defaults, results, and whether a listed GET is the top-level key command or a type-specific OP. It also identifies read-only operations and documents validation, lazy maintenance, and key-version behavior.

Operation payloads

The following examples use the public amaquet-cli JSON command format. Replace example:geo_spatial_index with the key used by your application.

Construction payloads

Use the payload below to initialize this type before issuing reads or type-specific operations.

CREATE

This payload initializes the value and must complete before its type-specific operations are used.

{
  "key": "example:geo_spatial_index",
  "type": "geo_spatial_index",
  "options": {}
}

Operations

Each request uses the OP envelope. The response is the type-specific value described in the complete operation contract.

OP ADD

Accepts id, point:{lat,lon}, optional string metadata map and returns true; replacing an ID moves its grid cell.

{
  "key": "example:geo_spatial_index",
  "operation": "ADD",
  "args": {
    "id": "manila",
    "point": {
      "Lat": 14.5995,
      "Lon": 120.9842
    },
    "metadata": {
      "country": "PH"
    }
  }
}

OP RADIUS

Accepts center, radius_meters, optional limit:100 and returns distance-sorted hits with distance_meters.

{
  "key": "example:geo_spatial_index",
  "operation": "RADIUS",
  "args": {
    "center": {
      "Lat": 14.5995,
      "Lon": 120.9842
    },
    "radius_meters": 1000,
    "limit": 10
  }
}

OP REMOVE

Accepts id and returns whether the item existed.

{
  "key": "example:geo_spatial_index",
  "operation": "REMOVE",
  "args": {
    "id": "manila"
  }
}

OP BOX

Accepts a bounding box and returns ID-sorted items inside inclusive bounds.

{
  "key": "example:geo_spatial_index",
  "operation": "BOX",
  "args": {
    "box": {
      "MinLat": 14.0,
      "MinLon": 120.0,
      "MaxLat": 15.0,
      "MaxLon": 122.0
    }
  }
}

OP POLYGON

Accepts polygon points and returns ID-sorted items inside the polygon.

{
  "key": "example:geo_spatial_index",
  "operation": "POLYGON",
  "args": {
    "points": [
      {
        "Lat": 14.5,
        "Lon": 120.9
      },
      {
        "Lat": 14.7,
        "Lon": 120.9
      },
      {
        "Lat": 14.6,
        "Lon": 121.1
      }
    ]
  }
}

Top-level read payload

GET reads the current value without changing it:

{
  "key": "example:geo_spatial_index"
}

Key lifecycle payloads

These commands apply to the key regardless of its registered type:

• TYPE: {"key":"example:geo_spatial_index"} — returns the wire type.
• EXISTS: {"key":"example:geo_spatial_index"} — reports whether the key exists.
• EXPIRE: {"key":"example:geo_spatial_index","ttl_ms":5000} — assigns a five-second TTL.
• TTL: {"key":"example:geo_spatial_index"} — returns the remaining TTL in milliseconds.
• PERSIST: {"key":"example:geo_spatial_index"} — removes the TTL.
• DEL: {"keys":["example:geo_spatial_index"]} — deletes the key.

For defaults, validation, result shapes, and persistence classification, see the complete operation contract.

Key lifecycle

The key participates in TYPE, EXISTS, TTL, EXPIRE, PERSIST, and DEL. Top-level GET returns the type’s direct public value or a synchronized snapshot.
