Currently this is not supported. If you want to do incremental fold-in of
new data you would need to do it outside of Spark (e.g. see this
discussion:
https://mail-archives.apache.org/mod_mbox/spark-user/201603.mbox/browser,
which also mentions a streaming on-line MF implementation with SGD).

Sean's old Myrrix slides contain an overview of the fold-in math:

Yes, really interesting discussion.
It would be really interesting to compare the performance of alternative
architectures. Specifically, I've found that Elasticsearch is a great
option for analytic workloads - it doesn't support SQL (joins in
particular), but its aggregation and arbitrary filteri
