Interface Summary

Interface	Description
Dataset<E>	A logical representation of a set of data entities.
DatasetReader<E>	A stream-oriented dataset reader.
DatasetWriter<E>	A stream-oriented dataset writer.
Flushable	A writer that can guarantee data is present on data nodes.
PartitionView<E>	A PartitionView is a subset of a Dataset that corresponds to a single partition, with a location.
RandomAccessDataset<E>	A Dataset that supports random access operations on entities.
RefinableView<E>	A RefinableView specifies a subset of a Dataset by one or more logical constraints.
Signalable<E>	Signalable views may signal consumers when their underlying data is ready for consumption.
Syncable	A writer that can guarantee data is persisted to disk.
View<E>	A View is a subset of a Dataset.

Class Summary

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 Summary

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 Summary

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.
