Example 1 with ExecutorProvider

use of io.mycat.calcite.ExecutorProvider in project Mycat2 by MyCATApache.

the class ObservablePlanImplementorImpl method executeQuery.

@Override

    AsyncMycatDataContextImpl.SqlMycatDataContextImpl sqlMycatDataContext = new AsyncMycatDataContextImpl.SqlMycatDataContextImpl(context, plan.getCodeExecuterContext(), drdsSqlWithParams);
    ExecutorProvider executorProvider = MetaClusterCurrent.wrapper(ExecutorProvider.class);
    PrepareExecutor prepare = executorProvider.prepare(plan);
    if (context.isVector()) {

        return response.sendVectorResultSet(observable1.getMycatRowMetaData(), observable1.getObservable());
    } else {
        ArrayBindable arrayBindable = prepare.getArrayBindable();
        Observable<MysqlPayloadObject> observable1 = PrepareExecutor.getMysqlPayloadObjectObservable(arrayBindable, sqlMycatDataContext, plan.getMetaData());
        Observable observable = mapToTimeoutObservable(observable1, drdsSqlWithParams);
