I can't say for sure but I believe I've stored more than 1 MB into a Text data member.
According to the javadoc<http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/datastore/Text.html> Text types are not limited to the 1MB max Entity size limit. Text wraps around a string of unlimited size. Ordinary Java strings stored > as properties in Entity objects are limited to 500 characters. However, > Text objects can also be stored in properties, and are unlimited in size. > However, they will not be indexed for query purposes. > On Fri, Jan 7, 2011 at 8:05 PM, 风笑雪 <[email protected]> wrote: > Hi Nicky, > > The max size of an entity is 1MB, so all of its properties cannot exceed > 1000000 bytes. > > ---------- > keakon > > My blog(Chinese): www.keakon.net > Blog source code: https://bitbucket.org/keakon/doodle/ > > > > On Sat, Jan 8, 2011 at 6:13 AM, Nicky <[email protected]> wrote: > >> It seems that the Text property is limited to 1000000 characters.
