Main Improvements

Support Druid SQL(#1099)

Now use SQL for querying Druid in the Metatron Workbench! Create “Druid” data connection for using it. It’s super easy and convenient. No need to set in the low level.

Create datasource with multiple sheets in Excel (#748)

From this version, now you can make “multiple sheets” of Excel file to “multiple datasets” at once in Metatron Data Preparation. Just select sheets when making dataset with excel file. Selected sheets are made into individual datasets automatically.

Support timezone for field of timestamp type (#1193)

Before 3.2.0-rc, If the timestamp type is included in the loaded data source, you can not check the user-based time zone reference when viewing data on the dashboard because the timezone is not set. From now on, data source creator can specify a timezone for the timestamp type in the data source, and the user can view the time value according to the user browser timezone through the dashboard.
