Interface Summary

Interface	Description
HoodieRecordCompatibilityInterface
HoodieRecordMerger	HoodieMerge defines how to merge two records.
HoodieRecordPayload<T extends HoodieRecordPayload>	Every Hoodie table has an implementation of the HoodieRecordPayload This abstracts out callbacks which depend on record specific logic.
OperationModeAwareness	In some cases, the Hudi engine needs to know what operation mode the current merging belongs to.

Class Summary

Class	Description
AWSDmsAvroPayload	Provides support for seamlessly applying changes captured via Amazon Database Migration Service onto S3.
BaseAvroPayload	Base class for all AVRO record based payloads, that can be ordered based on a field.
BaseFile	Represents common metadata about base-file.
BootstrapBaseFileMapping	POJO storing (partitionPath, hoodieFileId) -> external base file path.
BootstrapFileMapping	Value stored in the bootstrap index.
CleanFileInfo	File info for clean action.
ClusteringGroupInfo	Encapsulates all the needed information about a clustering group.
ClusteringOperation	Encapsulates all the needed information about a clustering file slice.
CompactionOperation	Encapsulates all the needed information about a compaction and make a decision whether this compaction is effective or not.
ConsistentHashingNode	Used in consistent hashing index, representing nodes in the consistent hash ring.
DefaultHoodieRecordPayload	Default payload.
DeleteRecord	Delete record is a combination of HoodieKey and ordering value.
EmptyHoodieRecordPayload	Empty payload used for deletions.
EventTimeAvroPayload	The only difference with DefaultHoodieRecordPayload is that is does not track the event time metadata for efficiency.
FileSlice	Within a file group, a slice is a combination of data file written at a commit time and list of log files, containing changes to the data file from that commit time.
FirstValueAvroPayload	Payload clazz that is used for Hudi Table.
HoodieArchivedLogFile	The hoodie archived log file.
HoodieAvroIndexedRecord	This only use by reader returning.
HoodieAvroPayload	This is a payload to wrap a existing Hoodie Avro Record.
HoodieAvroRecord<T extends HoodieRecordPayload>	Implementation of HoodieRecord using Avro payload.
HoodieAvroRecordMerger	Record merger for Hoodie avro record.
HoodieBaseFile	Hoodie base file - Represents metadata about Hudi file in DFS.
HoodieColumnRangeMetadata<T extends Comparable>	Hoodie metadata for the column range of data stored in columnar format (like Parquet) NOTE: Comparable is used as raw-type so that we can handle polymorphism, where caller apriori is not aware of the type HoodieColumnRangeMetadata is associated with
HoodieCommitMetadata	All the metadata that gets stored along with a commit.
HoodieConsistentHashingMetadata	All the metadata that is used for consistent hashing bucket index
HoodieDeltaWriteStat	Statistics about a single Hoodie delta log operation.
HoodieEmptyRecord<T>
HoodieFileGroup	A set of data/base files + set of log files, that make up a unit for all operations.
HoodieFileGroupId	Unique ID to identify a file-group in a data-set.
HoodieIndexDefinition	Class representing the metadata for a functional or secondary index in Hudi.
HoodieIndexMetadata	Represents the metadata for all functional and secondary indexes in Hudi.
HoodieKey	HoodieKey consists of
HoodieLogFile	Abstracts a single log file.
HoodieLogFile.LogFileComparator	Comparator to order log-files.
HoodieLSMTimelineManifest	Manifest entry for a version snapshot of the archived timeline.
HoodieLSMTimelineManifest.LSMFileEntry	A file entry.
HoodieMetadataRecordMerger	Record merger that accumulates metadata records.
HoodieMetadataWrapper	Wrapper for Hudi metadata.
HoodiePartitionMetadata	The metadata that goes into the meta file in each partition.
HoodiePayloadProps	Holds payload properties that implementation of HoodieRecordPayload can leverage.
HoodiePreCombineAvroRecordMerger	Record merger for Hoodie avro record.
HoodieRecord<T>	A Single Record managed by Hoodie.
HoodieRecordDelegate	Delegate for HoodieRecord.
HoodieRecordGlobalLocation	Similar with HoodieRecordLocation but with partition path.
HoodieRecordLocation	Location of a HoodieRecord within the partition it belongs to.
HoodieReplaceCommitMetadata	All the metadata that gets stored along with a commit.
HoodieRollingStat	A model class defines hoodie rolling stat.
HoodieRollingStatMetadata	This class holds statistics about files belonging to a table.
HoodieWriteStat	Statistics about a single Hoodie write operation.
HoodieWriteStat.RuntimeStats	The runtime stats for writing operation.
MetadataValues
OverwriteNonDefaultsWithLatestAvroPayload	subclass of OverwriteWithLatestAvroPayload.
OverwriteWithLatestAvroPayload	preCombine - Picks the latest delta record for a key, based on an ordering field; combineAndGetUpdateValue/getInsertValue - Simply overwrites storage with latest delta record
OverwriteWithLatestMerger	Avro Merger that always chooses the newer record
PartialUpdateAvroPayload	Payload clazz that is used for partial update Hudi Table.
RewriteAvroPayload	Default payload used for rewrite use cases where we don't change schema.
