I want to query using null value as filter but in druid 0.17.0 version i am facing some issues
For Query 1 using “value”: null
I get all result
For Query 2 using “value”: “null” :
I get values having null as substring, but not actual null values
For Query 3 using “value”: “”, :
I get all values
Can someone help in this ?
PS : We have null value for this dimensions, can get those values without using filters.
