Vladimir Ozerov updated IGNITE-6020:
------------------------------------
Fix Version/s: (was: 2.2)
> SQL: client should request first pages on query execution instead of first
> cursor read
> --------------------------------------------------------------------------------------
>
> Key: IGNITE-6020
> URL: https://issues.apache.org/jira/browse/IGNITE-6020
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Affects Versions: 2.1
> Reporter: Vladimir Ozerov
>
> Currently we request first data blocks form server nodes on first cursor
> access. However, user code might want to execute a query, and access the
> cursor after some delay, in hope that asynchronous execution will do the
> trick.
> For this reason, we should start requesting pages eagerly on "execute"
> command rather than on cursor access.
> {code}
> try (QueryCursor cursor = cache.execute(...)) { // <-- Should be here
> ...
> for (List<Object> row : cursor) { // <-- But currently here
> ...
> }
> }
> {code}
