@SandeepKSingh ,

glide.sc.multirow_set.rows.size is an undocumented property and this should be used with caution.

There is a reason for keeping the row limit to 50. Based on our analysis we have found that system performance will start degrading exponentially when the size increases more than 50. Hence the limit has been set to 50.

So, if someone is increasing the limit more than 50, it will have performance implications. 

Note -

I don't think as per the new versions you will be able to add more than 50 rows weather its via system property or variable set attribute.

If you try to do so, it will give you error - 

Maximum row limit defined for max_rows attribute exceeds the instance level limit
