MongoDB nested Object field depth limit

Question

If we have the following JavaScript object:

var obj = {

  field: {
           field: {
                    field: {
                              field: {...}
                            }
                  }
          }
          }

how deep can MongoDB go?

I think it can go until you hit the 16MB document size limit. — DaveStSomeWhere, Feb 18 '15 at 06:08

In accordance with the official documentation MongoDB supports 100 levels of nesting for BSON documents. Beside this there's a size limitation for a single document which is 16 megabytes.

If you are interested in storing larger documents you should read about GridFS.
