Push To Queue Back (LCC.kvdb.queue.push_back)

Signature​

size, err = LCC.kvdb.queue.push_back(name, value, timeout?)

Parameters​

  • name
    String. Queue name (non-empty, max 256 bytes).
  • value
    String, or a continuous string array. Strings must be valid UTF-8.
  • timeout
    Number, optional. Request timeout in seconds, default 60.

Returns​

  • size
    Number. Queue length after the push; nil on failure.
  • err
    String or nil. Error description when the call fails.

Notes​

Pushes an item onto the tail of the queue.
Batch pushes preserve array order. For example, {"a", "b"} becomes the new tail ..., a, b. Shares the same constraints as push_front.

Example​

local size, err = LCC.kvdb.queue.push_back("pending", "task#2")
if not size then
    error(err)
end

local batch_size, batch_err = LCC.kvdb.queue.push_back("pending", {"task#3", "task#4"})
