> Key: DRILL-5221
> URL: https://issues.apache.org/jira/browse/DRILL-5221
> Project: Apache Drill
> Issue Type: Improvement
> Components: Client - C++
> Affects Versions: 1.9.0
> Reporter: Laurent Goujon
> Assignee: Laurent Goujon
> Labels: ready-to-commit
> Fix For: 1.10.0
>
>
> When user is calling the cancel method of the C++ client, the client wait for
> a message from the server to reply back with a cancellation message.
> In case of queries taking a long time to return batch results, it means
> cancellation won't be effective until the next batch is received, instead of
> cancelling right away the query (assuming the query id has already been
> received, which is generally the case).
> It seems this was foreseen by [~vkorukanti] in his initial patch
> (https://github.com/vkorukanti/drill/commit/e0ef6349aac48de5828b6d725c2cf013905d18eb)
> but was omitted when I backported it post metadata changes.
