History

Gian Merlino d3a3b7ba0c Add virtual column types, holder serde, and safety features. (#3823 )

* Add virtual column types, holder serde, and safety features.

Virtual columns:
- add long, float, dimension selectors
- put cache IDs in VirtualColumnCacheHelper
- adjust serde so VirtualColumns can be the holder object for Jackson
- add fail-fast validation for cycle detection and duplicates
- add expression virtual column in core

Storage adapters:
- move virtual column hooks before checking base columns, to prevent surprises
  when a new base column is added that happens to have the same name as a
  virtual column.

* Fix ExtractionDimensionSpecs with virtual dimensions.

* Fix unused imports.

* CR comments

* Merge one more time, with feeling.
