| Class | Description |
|---|---|
| ColumnMapping |
A descriptor for an entity's column mappings, which defines how an entity
maps to a columnar store.
|
| ColumnMapping.Builder |
A fluent builder to aid in constructing a
ColumnMapping. |
| DatasetDescriptor |
The structural definition of a
Dataset. |
| DatasetDescriptor.Builder |
A fluent builder to aid in the construction of
DatasetDescriptors. |
| Datasets |
Methods for working with
Dataset instances. |
| FieldMapping |
Represents how to store a Schema field.
|
| Format |
The data format used for encoding the data in a
Dataset. |
| Formats |
Contains constant definitions for the standard
Format instances
supported by the library. |
| Key |
A key for retrieving entities from a
RandomAccessDataset. |
| Key.Builder |
A fluent builder to aid in the construction of
Key objects. |
| PartitionStrategy |
The strategy used to determine how a dataset is partitioned.
|
| PartitionStrategy.Builder |
A fluent builder to aid in the construction of
PartitionStrategys. |
| URIBuilder |
Builds dataset and view URIs
|
| Enum | Description |
|---|---|
| CompressionType |
Contains constant definitions for the standard compression types we support.
|
| FieldMapping.MappingType |
The supported Mapping Types, which control how an entity field maps to
columns in an HBase table.
|
| Exception | Description |
|---|---|
| ConcurrentSchemaModificationException |
Exception thrown when a schema modification collides with
another client trying to modify the schema of the same
dataset.
|
| DatasetException |
Exception thrown for dataset-related failures.
|
| DatasetExistsException |
Exception thrown when trying to create a dataset that already exists.
|
| DatasetIOException |
Exception thrown for dataset IO-related failures.
|
| DatasetNotFoundException |
Exception thrown to indicate that a dataset was not found.
|
| DatasetOperationException |
DatasetException thrown when an implementation-specific step fails
and prevents a dataset operation from completing successfully. |
| DatasetRecordException |
A DatasetException that signals that an individual record has failed.
|
| IncompatibleSchemaException |
Exception thrown when a schema update is not compatible
with the previous schema (or schemas) or with existing
datasets (if shared storage is used, for example).
|
| SchemaNotFoundException |
Exception thrown to indicate that there is a problem
finding a particular version of a schema.
|
| SerializationException |
Exception thrown when an object cannot be serialized to,
or deserialized from, its binary representation.
|
| TypeNotFoundException |
Exception thrown to indicate that there is a problem
finding a given type.
|
| UnknownFormatException |
Exception thrown when a Dataset is in an unknown format.
|
| ValidationException |
Exception thrown to indicate that there was a problem
parsing or validating a schema, partition strategy, or column mapping.
