Delete A Key (LCC.kvdb.dict.delete)

Signature

value, err = LCC.kvdb.dict.delete(name, key, timeout?)

Parameters

• name
  String. Dictionary name (non-empty, max 256 bytes).
• key
  String. Key to remove (must be valid UTF-8 and non-empty).
• timeout
  Number, optional. Request timeout in seconds, default 60.

Returns

• value
  String. Removed value; nil when the key was absent.
• err
  String or nil. Returns 'not found' when nothing was deleted.

Notes

Deletes the specified key and returns its previous value.
Handy for read-and-delete workflows when paired with get.

Example

local old, err = LCC.kvdb.dict.delete("settings", "temporary")
if old then
    LCC.log(2, "Removed stale config", old)
end
