> Currently we decode PLAIN encoded booleans as follow:
> {code:java}
> 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());
> }
> }
> {code}
> Ideally we should vectorize this.
