GEORADIUSBYMEMBER (deprecated)

GEORADIUSBYMEMBER key member radius <M | KM | FT | MI> [WITHCOORD]
  [WITHDIST] [WITHHASH] [COUNT count [ANY]] [ASC | DESC] [STORE key
  | STOREDIST key]

Available since:

3.2.0

Time complexity:

O(N+log(M)) where N is the number of elements inside the bounding box of the circular area delimited by center and radius and M is the number of items inside the index.

ACL categories:

@write, @geo, @slow,

This command is exactly like GEORADIUS with the sole difference that instead of taking, as the center of the area to query, a longitude and latitude value, it takes the name of a member already existing inside the geospatial index represented by the sorted set.

The position of the specified member is used as the center of the query.

Please check the example below and the GEORADIUS documentation for more information about the command and its options.

Note that GEORADIUSBYMEMBER_RO is also available since Redis 3.2.10 and Redis 4.0.0 in order to provide a read-only command that can be used in replicas. See the GEORADIUS page for more information.

Examples

RESP2/RESP3 Reply

One of the following:

• If no WITH* option is specified, an Array reply of matched member names
• If WITHCOORD, WITHDIST, or WITHHASH options are specified, the command returns an Array reply of arrays, where each sub-array represents a single item:
  • The distance from the center as a floating point number, in the same unit specified in the radius.
  • The Geohash integer.
  • The coordinates as a two items x,y array (longitude,latitude).

History

• Starting with Redis version 6.2.0: Added the ANY option for COUNT.
• Starting with Redis version 7.0.0: Added support for uppercase unit names.
