Retrieve Queue Length (LCC.kvdb.queue.size)

Signature

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

Parameters

• name
  String. Queue name (non-empty, max 256 bytes).
• timeout
  Number, optional. Request timeout in seconds, default 60.

Returns

• size
  Number. Current number of items; returns 0 for empty queues, or nil on failure.
• err
  String or nil. Error description when the call fails.

Notes

Returns the queue length directly, faster than calling list and counting.
Empty queues return 0.

Example

local size, err = LCC.kvdb.queue.size("pending")
if size then
    print("Queued:", size)
end
