-----------------------------------------
Summary: Sql. Implement thin client internal SQL API to support
reading script results
Key: IGNITE-26087
URL: https://issues.apache.org/jira/browse/IGNITE-26087
Project: Ignite
Issue Type: New Feature
Components: sql ai3
Reporter: Pavel Pereslegin
Currently SQL API over Thin Client supports script execution in a simplified
form (SQL_EXEC_SCRIPT). Users cannot iterate over the results of the script and
cannot use an explicit transaction.
To migrate the JDBC driver to use the SQL API over the thin client, we need to
extend the thin client's internal API and support iteration over the script
results.
* Extend SQL_EXEC operation to pass hasMoreResults flag from server to the
client (extend ClientAsyncResultSet with hasMoreResults flag).
* Introduce new operation SQL_CURSOR_NEXT_RESULTSET (similar to
JDBC_MORE_RESULTS) to allow switching to the next result set of the script.
Note: the script can be run inside a client transaction (this should work out
of the box but we should verify this case).
Public API should not be changed. Tests should use internal API.
