The Queue panel defines how items are stored in the queue.
The following properties are on the Queue panel:
This is the maximum number of flow items the queue can hold at once.
This menu defines how the flow items are placed in the queue visually. It has the following options:
This number defines the height where the queue begins placing flow items that are being stacked vertically or inside the queue.
If this box is checked the queue will act as a "last in first out" (LIFO) queue, otherwise it will act as a first in first out (FIFO) queue.
If this box is checked, the queue will accumulate flow items into a batch before releasing them downstream. Accumulation continues until either the target batch size is met or the max wait time expires. If this box is not checked, no batching will occur, and flow items may leave as soon as downstream objects are available.
This number defines the size of the batches that the queue will gather before sending the flow items downstream. Flow items are sent downstream individually.
This number is the maximum length of time that the queue will wait before sending the flow items downstream. If this time expires and the batch size has not been met, the currently collected batch will be released anyway. If 0 is specified in this field, then there is no maximum wait time, or in other words the queue will wait indefinitely.
If this box is checked the queue will not allow new flow items to enter until the entire current batch has left.
