What is the maximum size of a single BlobProperty in appengine? I'm not talking about the Blobstore API, I mean the BlobProperty property class
Please add a link that supports your answers.
The limit is 1 megabyte. The docs are here .
Like db.Text, the value of db.Blob can be up to 1 megabyte, but it is not indexed and cannot be used in filters or sort orders. The Db.Blob class takes str as an argument to its constructor. Blobs are modeled using the BlobProperty class.
