use of org.apache.drill.exec.physical.rowSet.RowSet.SingleRowSet in project drill by apache.

the class TestResultSetLoaderOmittedValues method testSkipRows.

/**
 * Test that omitting the call to saveRow() effectively discards
 * the row. Note that the vectors still contain values in the
 * discarded position; just the various pointers are unset. If
 * the batch ends before the discarded values are overwritten, the
 * discarded values just exist at the end of the vector. Since vectors
 * start with garbage contents, the discarded values are simply a different
 * kind of garbage. But, if the client writes a new row, then the new
 * row overwrites the discarded row. This works because we only change
 * the tail part of a vector; never the internals.
