Re: [january-dev] IDataset <-> python

[<Peter.Chang@xxxxxxxxxxxxx>]

Hi Scott,

We do have and use two mechanisms for communicating with Python: xml-rpc and Py4J. At the moment, they are part of Dawn Science (https://github.com/DawnScience/scisoft-core) and are based on saving the data to a filesystem that is accessible to both sides.

The next version of January will be a major one though there has not been any discussion I am looking at a March release.

Best regards,
 Peter

Subject: [january-dev] IDataset <-> python

Hi Folks,

Is there any existing work on going between an IDataset instance (in 
java) and a Dataset instance in Python using Py4j?   We are using 
January to build an IoT data analytics framework that is built on 
java/OSGi/kura/our stuff.   It includes a way to dynamically 
create/add/remove osgi services that pass IDataset instances between components to perform various analytics.

One thing that we might be interested in doing is having these osgi services implemented via Python...which would necessitate exchanging IDataset <-> Python dataset instances.

Another question:   When is the next expected release of January?    
Will it be a major, minor, maintenance?

Thanksinadvance for any information.

Scott
