> Abort scans of closed connections at ScanningResultIterator
> -----------------------------------------------------------
>
> Key: PHOENIX-6776
> URL: https://issues.apache.org/jira/browse/PHOENIX-6776
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Kadir Ozdemir
> Assignee: Lokesh Khurana
> Priority: Major
>
> The server side paging feature introduced by PHOENIX-6211 breaks a scan into
> timed scan operations on the server side and returns an intermediate result
> for each operation. This intermediate result could be a valid result or a
> dummy result. The HBase scans are wrapped by ScanningResultIterator in
> Phoenix. If the next call on a scan returns a dummy or empty result,
> ScanningResultIterator ignores this result and call the next method on the
> scan again. However, if the Phoenix connection is closed, we should abort the
> scan instead of continuing scanning. This will result in timely abort of
> scans and release of resources (especially when phoenix.server.page.size.ms
> is set to a small value, e.g., 5 sec).
