JSON.OBJKEYS
Syntax
JSON.OBJKEYS key [path]
Time complexity: O(N) when path is evaluated to a single value, where N is the number of keys in the object, O(N) when path is evaluated to multiple values, where N is the size of the key
Return the keys in the object that's referenced by path
Required arguments
key
is key to parse. Returns null
for nonexistent keys.
Optional arguments
path
is JSONPath to specify. Default is root $
. Returns null
for nonexistant path.
Return
JSON.OBJKEYS returns an array of array replies for each path, an array of the key names in the object as a bulk string reply, or nil
if the matching JSON value is not an object.
For more information about replies, see Redis serialization protocol specification.
