Jackie-Jiang opened a new issue #4230: NULL value support for all data types URL: https://github.com/apache/incubator-pinot/issues/4230 Currently in Pinot we don't have real NULL value support, but use some special default values for NULL. For dimensions, the default value is the minimum value for numeric types, "null" for STRING, empty byte array for BYTES; for metrics, the default value is 0 for numeric types, empty byte array for BYTES. #4214 adds support to treat empty byte array as NULL for BYTES, but it's not the general way to support NULL for all data types. We should add another type of index to mark if the value is null, and apply that while filtering or fetching the values to skip all NULL values.
