org.apache.drill.exec.physical.resultSet.ResultVectorCache

Packages that use ResultVectorCache

Package	Description
org.apache.drill.exec.physical.impl.scan.file	Handles optional file metadata columns: implicit columns and partition columns.
org.apache.drill.exec.physical.impl.scan.project	Provides run-time semantic analysis of the projection list for the scan operator.
org.apache.drill.exec.physical.impl.scan.v3.file
org.apache.drill.exec.physical.impl.scan.v3.lifecycle	Implements the details of the scan lifecycle for a set of readers, primarily the process of resolving the scan output schema from a variety of input schemas, then running each reader, each of which will produce some number of batches.
org.apache.drill.exec.physical.resultSet	Provides a second-generation row set (AKA "record batch") writer used by client code to Define the schema of a result set. Write data into the vectors backing a row set.
org.apache.drill.exec.physical.resultSet.impl	Handles the details of the result set loader implementation.
