gortiz opened a new issue, #10652:
URL: https://github.com/apache/pinot/issues/10652
Pinot support for null support is configured at table level by setting
`tableIndexConfg.nullHandlingEnabled` to true in TableConfig.
By setting this to true, all columns in the table are treated as nullable.
Given that nullable columns negatively impact in the heap and/or other
optimizations, ideally, we should let users to individually decide the
nullability of each column.
In order to do that, we have to:
* Change NullValueIndexType.createDeserializer to actually read `indexes`
like other indexes does.
* Change places where `tableIndexConfg.nullHandlingEnabled` is read
(directly or indirectly) in order to use
`getIndex(StandardIndexes.nullValueVector()).isEnabled()`. This includes
* SegmentColumnarIndexCreator
* BaseDefaultColumnHandler.createDefaultValueColumnV1Indices
