Xikui Wang resolved ASTERIXDB-2124.
-----------------------------------
Resolution: Fixed
> 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;
