max size in BlobProperty (appengine)

Question

What is the maximum size of one BlobProperty in appengine? I'm not talking about of the Blobstore API, i'm referring to the property class BlobProperty

Answer 1

The limit is 1 megabyte. Docs here.

Like db.Text, a db.Blob value can be as large as 1 megabyte, but is not indexed, and cannot be used in query filters or sort orders. The db.Blob class takes a str value as an argument to its constructor. Blobs are modeled using the BlobProperty class.
