------------------------------
Summary: ACID: Delete deltas should not project the row struct
Key: HIVE-21779
URL: https://issues.apache.org/jira/browse/HIVE-21779
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 3.1.1, 4.0.0
Reporter: Gopal V
{code}
if (useDecimal64ColumnVector) {
this.batch = deleteDeltaReader.getSchema().createRowBatchV2();
} else {
this.batch = deleteDeltaReader.getSchema().createRowBatch();
}
{code}
Is creating a fully wide row-batch, despite the fact that all row columns have
to be NULL in a delete delta.
createRowBatch() should follow includes and avoid over-allocating column vrbs.
