--------------------------------
Summary: Enable vectorized read for
VectorizedPlainValuesReader.readBooleans
Key: SPARK-35867
URL: https://issues.apache.org/jira/browse/SPARK-35867
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.2.0
Reporter: Chao Sun
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.
