Package com.illumon.iris.importers

Class SinglePartitionImportTableFactory

java.lang.Object

com.illumon.iris.importers.ImportTableWriterFactoryBase

com.illumon.iris.importers.SinglePartitionImportTableFactory

All Implemented Interfaces:

ImportTableWriterFactory

public class SinglePartitionImportTableFactory
extends ImportTableWriterFactoryBase

This should be used when a non-null single partition value should be used for import.

The factory will always return this single partition in the getComputedColumnPartition(String) call.

This also means the getTableDestination(String) returns the same destination

SinglePartitionImportTableFactory

public SinglePartitionImportTableFactory(@NotNull
 String namespace,
 @NotNull
 String tableName,
 @NotNull
 ImportOutputMode outputMode,
 @NotNull
 TableDefinition tableDefinition,
 @NotNull
 String internalPartition,
 @NotNull
 String columnPartition)

Constructor.

Parameters:

namespace - The schema namespace

tableName - The schema tablename

outputMode - The selected mode (one of safe, append, replace)

tableDefinition - The schema table definition

internalPartition - Non-null internal partition that is needed to build the FullTableLocationKey

columnPartition - Non-null column partition used to build the FullTableLocationKey

Method Details

getTableDestination

public File getTableDestination(@Nullable
 String columnPartitionValue)

Description copied from interface: ImportTableWriterFactory

Get a File representing the path where the table will be written.

Parameters:

columnPartitionValue - the column partition to find the destination for

Returns:

a file at the path the table will be written.

getComputedColumnPartition

public String getComputedColumnPartition(@Nullable
 String inputColumnPartition)

Description copied from interface: ImportTableWriterFactory

The method is invoked to determine the partition value to which the current row of data needs to be associated. So in the case where user wants a single partition value for the import this should return that value. In other cases this may simply return the passed in value, however, it is possible to return null indicating that there is no valid column partition.

Parameters:

inputColumnPartition - the requested input partition

Returns:

the computed column partition
