I have upgraded to druid 29.0.1, I see a change in handling of null values compared to 25.0.0, any way I can retain the old null handling ?

check this one generic.useDefaultValueForNull: true

Used all these, but no luck @Igor Berman

we have this in common properties file

@pratush maheshwari You can revert to the previous behavior by setting

druid.generic.useDefaultValueForNull

to

true

. This property affects both storage and querying, and must be set on all Druid service types to be available at both ingestion time and query time. Reverting this setting to the old value restores the previous behavior without reingestion. https://druid.apache.org/docs/latest/release-info/upgrade-notes/#sql-compatibility
