----------------------------------------
Summary: Feed fails to start when filter and index both exist on
one field
Key: ASTERIXDB-2124
URL: https://issues.apache.org/jira/browse/ASTERIXDB-2124
Project: Apache AsterixDB
Issue Type: Bug
Reporter: Steven Jacobs
Assignee: Xikui Wang
The following gives an internal error, but works successfully when either the
index or the filter are removed from the DDLs:
drop dataverse channels if exists;
create dataverse channels;
use dataverse channels;
create type UserLocation as closed {
recordId: integer,
location: circle,
userName: string,
timeStamp: datetime
};
create dataset UserLocations(UserLocation)
primary key recordId with filter on timeStamp;
create index time2 on UserLocations(timeStamp);
create feed LocationFeed using socket_adapter
(
("sockets"="127.0.0.1:10009"),
("address-type"="IP"),
("type-name"="UserLocation"),
("upsert-feed"="true"),
("format"="adm")
);
connect feed LocationFeed to dataset UserLocations;
start feed LocationFeed;
