Interface Summary

Interface	Description
BlockAllocator	Defines the interface that should be implemented by all reference counting Apache Arrow resource allocators that are provided by this SDK.
BlockAllocator.BatchGenerator	Used to generate a batch in a leak free way using the BlockAllocator to handle the boiler plate aspects of error detection and rollback.
BlockAllocatorRegistry	Used to track BlockAllocators in transactional environments where you want tighter control over how much memory a particular transaction uses.
BlockSpiller	Used to write blocks which may require chunking and optionally spilling via a secondary communication channel.
BlockWriter	Defines an abstraction that can be used to write to a Block without owning the lifecycle of the Block.
BlockWriter.RowWriter	The interface you should implement for writing to a Block via the inverted ownership model offered by BlockWriter.
FieldResolver	Assists in writing values for complex types like List and Struct by providing a way to extract child field values from the provided complex value.

Class Summary

Class	Description
ArrowSchemaUtils	Utility class for dealing with Arrow Schemas
ArrowTypeComparator	This utility class can be used to implement a comparator for various Apache Arrow typed values.
AthenaFederationIpcOption
Block	This class is used to provide a convenient interface for working (reading/writing) Apache Arrow Batches.
BlockAllocatorImpl	Basic BlockAllocator which uses reference counting to perform garbage collection of Apache Arrow resources.
BlockUtils	This utility class abstracts many facets of reading and writing values into Apache Arrow's FieldReader and FieldVector objects.
DateTimeFormatterUtil	Provides utility methods relating to formatting strings to date/datetime type
FieldBuilder	Convenience builder that can be used to create new Apache Arrow fields for common types more easily than alternative methods of construction, especially for complex types.
RecordBatchSerDe	Deprecated. ArrowRecordBatchSerDeV3 should be used instead
S3BlockSpiller	Implementation of BlockSpiller which spills Blocks from large results to S3 with optional AES-GCM encryption.
S3BlockSpillReader
SchemaAware	Defines a component that is aware of Apache Arrow Schema.
SchemaBuilder	Convenience builder that can be used to create new Apache Arrow Schema for common types more easily than alternative methods of construction, especially for complex types.
SchemaSerDe	Deprecated. SchemaSerDeV3 should be used instead
SimpleBlockWriter	Used to write a single Block using the BlockWriter programming model.
SpillConfig	Used to configure Spill functionality.
SpillConfig.Builder
TimeZoneKey	Class for representing timezone to be used in encoding datetime value and timezone value to a single long Source: Presto TimeZoneKey
