node execute limit

Question

I need to execute node consistently, but I get this error I get the error "The number of tasks per node would exceed the limit of 1000". Could someone help me with it? 
 there are config details

As per my understanding, it's worth having such limitations OOTB, otherwise assume what if I have a variable having 10,000 or may be more items and have applied MNI over this, this will slow down the whole environment and will impact other applications as well as their objects performance.

Hence I believe, it's better if you configure a manual batch to execute MNI for only 100 items at once and then loop the process flow to a timer to hold this process for couple of minutes (can be identified, based on number of applications/objects/performance of the server) and again process the MNI for Next set of 100 items.

Also, try defining a constant of type Number(Integer) and mark it as an environment variable, so that you can define the MNI batch max limit dynamically (as this can vary from one to another environment, because one env system configurations can be different than the other).

In this way, you will be able to complete your job without impacting the server performance.

Hope this will help.

MNI with batching is a possible solution, however you wind up with MNI squared. While none of your other users might notice and think the system is broken, the user waiting for 10,000 records to be processed will think the system is broken, waiting for 100 sets of 100Loops. You'll also have to cofigure something to alert the user minutes later when the processing is finally done. 
 
Worse still, far be it for someone to have more than 1,000,000 records, but you'll have to do MNI cubed if anyone ever does. At 900,000 records you're going to have to implement it. 
 
Or just don't. Or query all the records you want (several million if need be) in 1 script task and process them all in a single in a!forEach in 1 script task at several thousand times the pace. 
 
Again, I got a process that looped through 300 records using MNI from 3 or 4 minutes down to 40 miliseconds by switching to one a!forEach loop. If it's at all possible, switch to a!forEach.

In these cases i would recommend to perform these operation only asynchronous by configuring this node inside a sub-process, because this could be a heavy operation, and user cannot wait for that long. 
 
Also, It depends upon what's next after the completion of this activity, is that the Task Assignment, or process simply terminates after processing the loop. 
 
Because if the next set of steps are related to Task assignment, then yes, user can't wait for that long and may suspect that there is something wrong happened behind the screen, but if the process terminates post processing this MNI then i think either the way should be fine (including performing this job asynchronous). 
 
Also, as per the recommended approach in terms of performance, Yes you should opt for a!forEach() over MNI, wherever applicable. 
 
But, just because you are making the use of forEach() doesn't mean that you should process the complete loop at once(if the data set is very huge), because this may also slow down your server performance. 
 
I believe one of the most important factor in terms of performance while looping is, what operation are you trying to perform, is that a normal manipulation job or interacting with the DB. 
 
But of course, a!forEach() stands better while compared to MNI, in terms of performance (wherever applicable).
