Problem description

I want to put some conditions or constraints in one of the table in multi-table evaluation. I have pasted the json format where i have put condition in bold in user table json. Is there any way to achieve the same since we are doing it for the single table?

{
"tables": {
"users": {
"fields": {
"user_id": {
"type": "id",
"subtype": "integer"
},
"country": {
"type": "categorical"
},
"gender": {
"type": "categorical"
},
"age": {
"type": "numerical",
"subtype": "integer"
}
},
"primary_key": "user_id",
"conditions":{"age" : 20}
},
"sessions": {
"fields": {
"session_id": {
"type": "id",
"subtype": "integer"
},
"user_id": {
"type": "id",
"subtype": "integer",
"ref": {
"table": "users",
"field": "user_id"
}
},
"device": {
"type": "categorical"
},
"os": {
"type": "categorical"
},
"minutes": {
"type": "numerical",
"subtype": "integer"
}
},
"primary_key": "session_id"
},
}
}

Hi @Puspak64, thanks for your question. We are tracking the issue of passing tabular constraints to HMA1 here. You can also find a workaround in the linked issue.

We don't currently support using conditions with multi-table, but are planning on adding that through conditional sampling, similar to what is currently supported in our single table models. We will track this feature request here.

I'm going to close out this issue in favor of the other two issues that are linked in my above comment. Please feel free to track the multi-table conditional sampling and constraint functionality there!
