updateStateByKey -- when the key is multi-column (like a composite key )

[shyla deshpande <de...@gmail.com>]

updateStateByKey - Can this be used when the key is multi-column (like a
composite key ) and the value is not numeric. All the examples I have come
across is where the key is a simple String and the Value is numeric.

Appreciate any help.

Thanks

Thanks Miguel for the response.

Works great. I am having a tuple for my key and the values are String and
returning String to the updateStateByKey.

I *think* you can return a map to updateStateByKey which would include your
fields.  Another approach would be to create a hash (like create a json
version of the hash and return that.)
