    Hey Chris,

    I am really enjoying working with durabletask functions. I want to get your thoughts on the message size limit (62KB) between the Orchestration and Activity. In your Fanout example of directory backup, what if the message payload size of the list of directories coming in from the Activity is larger than 62KB? What strategy would you suggest using to get around that limitation?

    @hornygoatweed: We plan on expanding the message size limitations to allow for arbitrarily large messages. That work is being tracked in Github here: https://github.com/Azure/azure-functions-durable-extension/issues/26. Until then, you can write your activity functions to store their results into something like blob storage, and then return a reference to the blob (e.g. the URL) from your activity functions.
