New Releases: Metatron Discovery 3.3.1 & 3.4.0(rc1)

Hello, users! We are back to you with new updates on Metatron Discovery. We have two versions ready – a new stable version 3.3.1 and a first release candidate of version 3.4.0. Explore our recent improvements:

Metatron Discovery 3.4.0 rc1

Support Black Theme

Apply black design theme and change global UI function (#2388)
Finally, you can change the UI theme mode easily with a toggle. The darker theme has many benefits. It improves visibility for users with low vision and those who are sensitive to bright light. Also, it makes easier to use the web in a low-light environment.

Introduce Engine Monitoring (Beta)

Introduce engine(druid) monitoring function (#1373)
We have been considering creating an administration tool to figure out how to manage our druid engine better. Although there is a web console for the original Druid, but we needed more! In our engine monitoring page, you are able to check the server status in the Druid cluster and get comprehensive statistics. Ingestion tasks are also checked with logs. From the 3.4.0-rc1 version, you can see Engine Monitoring from the Management menu. This feature is only allowed to users who are set to data-manager or have higher authorization. Because it is an beta feature, you need to configure to see this in your menu tab:

./conf/application-config.yaml
polaris:
extensions:
  lnb:
    - name: Engine Monitoring
