max number of items in an array attribute

hello I am using this code to read all the lines of a postgresSQL table (100 000 lines )

var columns = {
};
var result  = vmsTable.readRecords(columns, false);

this works and in 5 seconds my result variable is filled with the 100 000 lines

but if the result variable is replaced by an array attribute of type any the script gives me the error

[2018-03-14 12:37:21.219] [E] Workflow execution stack:

***

', state: 'failed', business state: 'null', exception: 'null'

*** End of execution stack.

and if I reduce the number of lines to about 3000 it works but the workflow is very long (for exemple to log each value )

is there a maximum number of lines to use in array attributes to avoid performance issues?
