>                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1588
>             Project: Apache AsterixDB
>          Issue Type: Bug

> Following ddl with 'autogenerated' will cause indexOutOfBoundary exception at the SocketFeed
part.

> drop dataverse feeds if exists; 
> create dataverse feeds;
> use dataverse feeds;
> create type TwitterUser if not exists as open\{
>     screen-name: uuid
> \};
> create dataset TwitterUsers1(TwitterUser) primary key screen-name autogenerated;
> create feed UserFeed1 using socket_adapter
> (
> 	("sockets"="127.0.0.1:10001"),
> 	("address-type"="IP"),
> 	("type-name"="TwitterUser"),
> 	("format"="adm")
> );
> use dataverse feeds;
> set wait-for-completion-feed "false";
> connect feed UserFeed1 to dataset TwitterUsers1
> {quote}
> The reason this happens is when SocketServerInputStream found no available bytes, it
will trigger the TupleForwarder to flush all tuples. org/apache/asterix/external/input/stream/SocketServerInputStream.java:70
> This causes the indexOutOfBoundary exception at org/apache/asterix/external/util/FeedUtils.java:123
> Same ddl without 'autogenerated' will work properly.
