    I want to load an email dataset into Azure ML for Text Classification.  I plan to store the data in Blob Storage.  Does anyone know the maximum length a string feature can support?

    Hello! I would use 2GB as the default .NET array limit as a first approximation of the maximum length.

    Note that this is from a Reader module - if you're providing it as an input to a web service's RRS endpoint the limit is drastically smaller due to the JSON serialization limitation.

    Anyway if you were handling that much data I expect you would be using the Batch endpoint :)
