Example 1 with AbstractMapVector

use of org.apache.drill.exec.vector.complex.AbstractMapVector in project drill by axbaretto.

the class VectorContainerBuilder method buildMap.

    // Creating the map vector will create its contained vectors if we
    // give it a materialized field with children. So, instead pass a clone
    // without children so we can add them.

    // Don't get the map vector from the vector cache. Map vectors may
    // have content that varies from batch to batch. Only the leaf
    // vectors can be cached.

        // repeated map.
