I realised a [Missing Value] node inside a loop (eg. [Group Loop]) is slowing down the processing speed.
Any tips on increasing the speed?
I am trying to loop through each Stock ID and replace missing values with the next values.
Any help is appreciated.
What exactly do mean by “slowing down”? Slower than without the node or that the Missing Value node is slower inside a loop than outside a loop?
Hi Stefan, thank you for your reply and apologies for not being clear.
I meant that the Missing Value node is slower inside a loop.
I am using a Group Loop for 70,000 unique item code and I am using the Missing Value to fill up missing information for certain rows.
On average, it is taking 1 second per loop.
I am just wondering if there is a better/more efficient way to do this.
Any help would be appreciated.
Hi there @bentheknimeuser,
I guess the parallel version of Group Loop node would help. Luckily there is a workaround provided in this topic.
Additionally if you are maybe using option Use disk based statistics in Missing Value node turn it off as it is slowing execution
