Roadmap for 2019

beyond MDM

We are planning to add search function to the mdm management, and we will try various things to improve the usability of search.


Goals are improving chart properties, implementing real-time dashboards, improving multi-data and filter usability, and enhancing map charts. Especially until February, we aim to implement spatial operations on map charts.

Self service

We will support data source management for individual users in the workspace to enable workspace-centric data navigation. The data prep function will also be moved from the management menu to the workspace menu so that individual users can also pre-process the data. This will ensure that all users of Discovery will be able to process data in the workspace from pre-processing to visualization.


The Metatron component will be an extensible structure so that orchestration will be possible.

Plan for the next iteration

Is there a feature to monitor the druid’s condition?
– It didn’t come out today, but we are planning to develop it.

There is a need to monitor metatron charts as a dashboard.
– Since the current discovery function is too complicated, the monitoring function will be opened after the first half including anomaly detection function, simple analysis function, and monitoring dashboard

I want to draw a picture in the map or upload my own geo data.
– In addition to filtering data on the chart creation screen, there is a need for a different method in the chart analysis screen to perform spatial calculations. We will try to make solution.
