[jira] [Created] (ASTERIXDB-1327) Spatial-intersect between point and circle not working correctly

Steven Jacobs created ASTERIXDB-1327:
----------------------------------------

             Summary: Spatial-intersect between point and circle not working correctly
                 Key: ASTERIXDB-1327
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1327
             Project: Apache AsterixDB
          Issue Type: Bug
            Reporter: Steven Jacobs


The first query returns a large set of results. The second returns nothing

for $report in dataset EmergencyReports
for $location in dataset UserLocations
where $report.emergencyType = "earthquake"
let $circle := create-circle($location.location,.1)
where spatial-intersect($report.impactZone, $circle)
return {
	"user at":$location.location,
	"report at":$report.impactZone
}

for $report in dataset EmergencyReports
for $location in dataset UserLocations
where $report.emergencyType = "earthquake"
where spatial-intersect($report.impactZone, $location.location)
return {
	"user at":$location.location,
	"report at":$report.impactZone
}


Here are the DDL statements. I will attach the two datasets:
drop dataverse channels if exists;
create dataverse channels;
use dataverse channels;

create type UserLocation as closed {
	recordId: uuid,
	location: point,
	user-id: string,
	timeoffset: float
}


create type EmergencyReport as closed {
	reportId: uuid,
	severity: int,
	impactZone: circle,
	timeoffset: float,
	duration: float,
	message: string,
	emergencyType: string
}


create dataset UserLocations(UserLocation)
primary key recordId autogenerated;


create dataset EmergencyReports(EmergencyReport)
primary key reportId autogenerated;

load dataset UserLocations using localfs (("path"="asterix_nc1:///Users/stevenjacobs/Desktop/EmergencyDataset/UserLocationsShort.adm"),("format"="adm"));

load dataset EmergencyReports using localfs(("path"="asterix_nc1:///Users/stevenjacobs/Desktop/EmergencyDataset/EmergencyReports.adm"),("format"="adm"));
