Metatron Discovery 3.3.0
To analyze data by yourself, searching the data sets you want to analyze is always important. Metatron Discovery 3.3.0 now supports searching data based on their meta information. It is possible to see data source popularities and recommendations to use personally.
If you want to use this beta exploration, you need to toggle on the menu by adding configuration like below:
./conf/application-config.yaml polaris: extensions: lnb: - name: Explore Data
Add additional options when creating data sources
Schema modifications have been improved in the ingestion stage. You can edit the column names, add or delete columns freely.
Also, You can now append more rows or overwrite the existing datasource. If the schema of the data source you want to re-ingest is different from the existing data source’s, then the entire data will be overwritten.
Improved metadata management
Metatdata improves your analytical performance. It tells you about more details about datasource in your system. From the 3.3.0 release, you can add and manage metadata information linked with datasource which is in all the database connections supported by Metatron Discovery. Through those MDM feature, data managers can give insights with detailed descriptions to the analysts!
We prepared the metadata detail sample to our instances. Choose metadata source in metadata main page and go to metadata detail. You are able to view and download sample data Check out now!
Improved notebook functionality
No more need a server host name and a port to create a notebook connection. Only an URL is needed to connect to your notebook server. Also, you can add both the Jupyter and Zeppelin notebook connections at the same time.
