Description

Currently we decode PLAIN encoded booleans as follow:

  public final void readBooleans(int total, WritableColumnVector c, int rowId) {
    // TODO: properly vectorize this
    for (int i = 0; i < total; i++) {
      c.putBoolean(rowId + i, readBoolean());
    }
  }

Ideally we should vectorize this.
