--------------------------------------------
Summary: IRecordReader interface needs revision
Key: ASTERIXDB-1416
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1416
Project: Apache AsterixDB
Issue Type: Bug
Components: AsterixDB
Reporter: Abdullah Alamoudi
Assignee: Abdullah Alamoudi
The IRecordReader interface have an iterator like methods:
1. hasNext()
2. next()
However, it is possible for hasNext() to return true and next() to return null,
meaning that it has next but next is not ready. This is confusing and should be
fixed. Particularly, the right thing would be for hasNext() only to return true
when it has something immediately ready. If it doesn't have something ready, it
should block.
An alternative would be to re-design the interface.
