[jira] [Updated] (ATLAS-4750) [Relationship Search] Relationship search isNull case doesn't consider null strings
[ https://issues.apache.org/jira/browse/ATLAS-4750?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Abhishek Pal updated ATLAS-4750:
--------------------------------
Description:
Currently Atlas supports relationship search where we can search entities by their relationships.
We can use various filters to search for the relationship, where one such filter is a condition of "isNull".
If there are relationships where a string type attribute is set to *""* (null string), it considers this as non-null.
For example if there is are two relationships with attributes:
* relation_X
** "type_str": ""
* relation_Y
** "type_str": null
and we search by condition:
{code:java}
{
"attributeName": "type_str",
"operator": "isNull",
"attributeValue": ""
}
{code}
we get only *relation_Y*
Whereas since *relation_X* has
{panel}
"type_str":""
{panel}
it is not treated as a null value and hence not returned.
This is also the case for {panel} "operator": "notNull" {panel} where we get the *relation_X*
Ideally this should also be considered a null type
