org.apache.hadoop.hive.ql.exec.vector.VectorizedRowBatch
A VectorizedRowBatch is a set of rows, organized with each column as a vector. It is the unit of query execution, organized to minimize the cost per row and achieve high cycles-per-instruction. The major fields are public by design to allow fast and convenient access by the vectorized query execution code.
