| Package | Description |
|---|---|
| org.apache.drill.exec.physical.resultSet.impl |
Handles the details of the result set loader implementation.
|
| org.apache.drill.exec.physical.resultSet.model.single |
This set of classes models the structure of a batch consisting
of single vectors (as contrasted with a hyper batch.) Provides tools
or metdata-based construction, allocation, reading and writing of
the vectors.
|
| org.apache.drill.exec.physical.rowSet |
Provides a set of tools to work with row sets.
|
| org.apache.drill.exec.vector.accessor |
Provides a light-weight, simplified set of column readers and writers that
can be plugged into a variety of row-level readers and writers.
|
| org.apache.drill.exec.vector.accessor.writer |
Implementation of the vector writers.
|
| org.apache.drill.exec.vector.accessor.writer.dummy |
This package provides a "dummy" set of writers.
