Should be fixed in IGNITE-23441
> Sql. Synchronous cancellation of a locally initiated request
> ------------------------------------------------------------
>
> Key: IGNITE-23778
> URL: https://issues.apache.org/jira/browse/IGNITE-23778
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Pavel Pereslegin
> Priority: Major
> Labels: ignite-3
>
> If query has opened cursor call to CancelHandle.cancel() will wait until
> something will be done with cursor (from the user side).
> For example:
> {code:java}
> @Test
> public void simpleCancelTest() {
> IgniteSql sql = igniteSql();
> CancelHandle cancelHandle = CancelHandle.create();
> CancellationToken token = cancelHandle.token();
> Statement statement = sql.statementBuilder()
> .query("SELECT * FROM system_range(0, 10000000000)")
> .build();
> try (ResultSet<SqlRow> rs = sql.execute(null, token, statement)) {
> // PROBLEM
> // We hang here until the user does something with the cursor.
> cancelHandle.cancel();
> try {
> while (rs.hasNext()) {
> rs.next();
> }
> fail("Exception was not thrown");
> } catch (SqlException expected) {
> assertEquals(Sql.EXECUTION_CANCELLED_ERR, expected.code());
> }
> }
> }
> {code}
> If you change {{cancelHandle.cancel();}} to {{cancelHandle.cancelAsync();}},
> the test will pass.
