Examples of org.apache.drill.exec.record.RecordBatch

org.apache.drill.exec.record.RecordBatch
A record batch contains a set of field values for a particular range of records. In the case of a record batch composed of ValueVectors, ideally a batch fits within L2 cache (~256k per core). The set of value vectors do not change unless the next() IterOutcome is a *_NEW_SCHEMA type. A key thing to know is that the Iterator provided by record batch must align with the rank positions of the field ids provided utilizing getValueVectorId();
