Using this demo

Steps to perform demo

Clone Repo/Download files
Navigate to directory
docker compose up -d –build
- Note: build can take a few minutes due to dependencies
Navigate to: http://localhost:61773/csp/user/_DeepSee.UI.Analyzer.zen?$NAMESPACE=USER&CUBE=HoleFoods.cube
Place some dimension on rows, DateOfSale for example
Select a cell that you would like to further analyze the data behind
Select PivotToJupyter custom action
After being navigated to the Jupyter notebook, play all cells

Install with ZPM

zpm "install pivottojupyter"

Installing with ZPM does not configure Python or the notebook server. It simply installs the demo KPI class. This means either the demo KPI will need to be modified for your configurations, or you will need to make configuration changes similar to what the container does.

The following python libraries are used: notebook pandas matplotlib seaborn sqlalchemy-iris.

Manual configurations for a notebook server are also needed. The KPI expects a notebook server to be listening on port 61888 (it is actually listening on port 8888 in the container, but the container exposes this as 61888). The KPI also places generated notebook files in <install dir>/mgr/<namespace>/notebooks, which means the notebook server needs to look in this directory for the files.

For extra details on how these are implemented in the container, continue reading the Implementation Guide.

Implementation Guide

There are two main components to this demo. The first is a custom action inside or IRIS BI. The second is a Jupyter notebook that uses data that was specified in the custom action.

Custom Action

Custom Actions come from code that is implemented in a “KPI Action Class”. This class is then pointed to by a cube so it can use the defined custom actions. In this example, the class PivotToJupyter.CustomKPIAction was created to implement the custom action. Inside of %OnDashboardAction, there is logic to pull the current query context out of the pContext object so either the selected cell on the pivot table, or the context of the entire pivot table will be used. Once this context is extracted, a new table is created based on the Listing results of the current query context. Then, a python method, GenerateNotebook is executed to generate the notebook that queries this new table. Finally, it uses the “newWindow” command to open a new browser window that points to the notebook server running in the container with the newly generated notebook.

Jupyter Notebook

The Dockerfile does two important steps for creating the notebook server:

RUN python3 -m pip install notebook pandas matplotlib seaborn sqlalchemy-iris - this installs dependencies for both hosting the notebook server as well as installing the python libraries that the demo code in the generated notebook uses.

CMD ["jupyter", "notebook", "--ip=0.0.0.0", "--port=8888", "--no-browser", "--allow-root", "--NotebookApp.token=''", "--ServerApp.root_dir=/usr/irissys/mgr/user/notebooks"] - this tells the container to run the notebook server when the container is started. I also needed to implement entrypoint.sh to ensure that iris-main is still executed so IRIS also starts with the container.
