Example 24 with MapContainer

use of com.hazelcast.map.impl.MapContainer in project hazelcast by hazelcast.

the class QueryRunner method runIndexOrPartitionScanQueryOnOwnedPartitions.

    // then we try to run using an index, but if that doesn't work, we'll try a full table scan
    // This would be the point where a query-plan should be added. It should determine f a full table scan
    // or an index should be used.
