Hi all, I think we are at the point where we should try to tackle Model as a service for Metron. As such, I created a JIRA and proposed an architecture for accomplishing this within Metron.
My inclination is to be data science language/library agnostic and to provide a general purpose REST infrastructure for managing and serving models trained on historical data captured from Metron. The assumption is that we are within the hadoop ecosystem, so: - Models stored on HDFS - REST Model Services resource-managed via Yarn - REST Model Services discovered via Zookeeper. I would really appreciate community comment on the JIRA ( https://issues.apache.org/jira/browse/METRON-265). The proposed architecture is attached as a document to that JIRA. I look forward to feedback! Best, Casey
