title: Javascript object maxium memory size
body: <p>Currently i am doing a simple db migration through Javascript. I find myself wanting to keep track of some simple id -> object maps to make less SQL db calls.</p>
  
  <p>So the question is, what is the maximum size of a javascript object in node?
  Say i have a very simple table with 2000 records. I am only interested in two columns, is it possible for me to just store all these values under a plain JS object that looks like {id1: {col1: "foo", col2: "bar"}, id2: {col1: "ss", col2: "bb"}} ??</p>
  
  <p>If 2000 is okay, what is the maximum that i can do?</p>
