Example 1 with QueryParseResult

use of com.hazelcast.jet.sql.impl.parse.QueryParseResult in project hazelcast by hazelcast.

the class CalciteSqlOptimizer method prepare.

@Override
public SqlPlan prepare(OptimizationTask task) {
    // 1. Prepare context.
    int memberCount = nodeEngine.getClusterService().getSize(MemberSelectors.DATA_MEMBER_SELECTOR);
    OptimizerContext context = OptimizerContext.create(task.getSchema(), task.getSearchPaths(), task.getArguments(), memberCount, iMapResolver);
    // 2. Parse SQL string and validate it.
    QueryParseResult parseResult = context.parse(task.getSql());
    // 3. Create plan.
    return createPlan(task, parseResult, context);
}

Example 2 with QueryParseResult
