Max length of String stored with App Engine?

google-app-engine, java, objectify

Solution

Objectify will automatically convert Strings of more than 500 characters to native Text storage. Be careful if you are indexing strings; Text objects are not indexed so the String > 500 chars will be unindexed.

Problem

When storing `String` fields with App Engine: - What is the maximum `length()` of the `String` that App Engine datastore can handle? - Also if using Objectify, is this max length the same or Objectify does some processing that affect this max length?
