Chunk Loop Run-for-time Loop Start

Loop start node to chunk table into blocks and run until a specified time period has elapsed. The user can specify the number of rows to process in each chunk, and the time period (dd:hh:mm:ss) after which the last iteration will start before. The loop will execute until that time period has elapsed, when no further rows will be processed. If connected to a Run-to-time Loop end, the unprocessed rows will be available directly in the final port of the loop end node.

Options

Chunking

Number of rows per chunk
The number of rows to be processed during each loop iteration

Expiry time

Run time (dd:hh:mm:ss):
The time period after which execution will finish (dd:hh:mm:ss)
Start value of iteration counter
Allows the user to manually set the value at which the iteration counter will start (does not affect the processing of the table!)
