you can filter the data you need by using PEventStore API or modifying the
DataSource.scala. Then train different engine instance with different
configuration.

I think the Java SDK already supports it creating events to a file, but
it's not documented.

Pat, would you explain more about the 'instanceId' as in
`pio register --variant path/to/some-engine.json --instanceId
some-REST-compatible-resource-id` ?
Currently PIO also has a concept of engineInstanceId, which is output of
train. I think you are referring to different thing, right?

as far as i understand, at high-level, kappa is more like a subset of

I guess your use case is not for real time label classify for unseen data?
batch prediction is basically the same as batch eval.

I agree that there is confusion regarding event server VS event storage
and the unclear usage definition of types of data storage (e.g. meta-data
vs model)
but i'm not sure if bundling Event Server with Engine Server (or Pat calls
it PredictionServer) is a good solution.
currently PIO has 3 "ty

thomas, if you always your own data store backend for events or your
application data, you don't have to use EventServer. Just implement a PIO
engine which directly reads from your data source.

yes. HBase is currently supported, which seems similar to Accumulo.
it s not difficult to add another storage backend support option - just
need to implement the stroage layer interface. Contribution is welcome!
