Hello Fabio,

what you describe sounds very possible, the easiest way to do it would be
to save your incoming data in HDFS as you already do if I understand
correctly,
and then use the batch ALS algorithm [1] to create your recommendations
from the static data, which you could do at regular intervals.

Regards,
Theodore
