Hello, Is Spark required only for "PIO TRAIN" or is it needed for serving the recommendations as well?
I am planning to run PredictionIO on AWS. So, thinking to run PredictionIO with Elastic search service and EMR. Wanted to know if we can use EMR only during the training phase and then serve the recommendations from another smaller instance running PredictionIO talking to the Elastic Search service. Is this possible? Please let me know. Thanks.
