Jackie-Jiang opened a new issue, #8699: URL: https://github.com/apache/pinot/issues/8699
When new columns are added to a pinot table, the server is able to automatically generate default columns for the new added columns. There are 2 types of default column that can be auto-generated: 1. New added column without transform function: default column will be filled with default null value (always dictionary encoded) 2. New added column with transform function (derived column): default column will be filled with values calculated based on the transform function There are 2 things not handled right now: 1. Generate default column raw forward index (not dictionary encoded) 2. Support transform function on another new added column: we need to calculate the dependency between new added columns, and generate them in sequence See `BaseDefaultColumnHandler` for details -- This is an automated message from the Apache Git Service.
