Re: store in riak, calculate with spark and feedback to riak

[Matt Digan]

Hi Julio,

Our Spark-Riak Connector is now publicly available. Check out the README
for an overview on how to interact with Riak from Spark:
https://github.com/basho/spark-riak-connector/blob/develop/README.md

Happy to answer more detailed questions if/when you have them.

Re: Using Riak KV with Amazon ML

[Matt Digan]

Hi Ricardo,

Full bucket read is not supported yet by Riak KV. If you're able to
upgrade, Riak TS does support that feature.

Otherwise, with Riak KV, you could use a range of 2i indexes. See
https://github.com/basho/spark-riak-connector/blob/master/docs/using-connector.md#reading-data-from-kv-bucket
for more info.
