All Classes and Interfaces

Class	Description
AbstractCommitInfo	Interface for objects that represents the base information for a commit.
AbstractMetadata	Interface for metadata actions in Delta.
AbstractProtocol	Interface for protocol actions in Delta.
AzureLogStore	LogStore implementation for Azure.
CatalogTrackedInfo
CloseableIterator<T>	:: DeveloperApi :: An iterator that may contain resources which should be released after use.
Commit	Representation of a commit file
CommitCoordinatorClient	The CommitCoordinatorClient is responsible for communicating with the commit coordinator and backfilling commits.
CommitFailedException	Exception raised by CommitCoordinatorClient.commit(LogStore, Configuration, TableDescriptor, long, Iterator, UpdatedActions)
CommitLimitReachedException	This exception is thrown by the UC client in case UC has reached the maximum number of commits that it is allowed to track (50 by default).
CommitResponse	Response container for CommitCoordinatorClient.commit(LogStore, Configuration, TableDescriptor, long, Iterator, UpdatedActions).
CoordinatedCommitsUtils
FileNameUtils	Helper for misc functions relating to file names for delta commits.
GCSLogStore	The LogStore implementation for GCS, which uses gcs-connector to provide the necessary atomic and durability guarantees: Atomic Visibility: Read/read-after-metadata-update/delete are strongly consistent for GCS. Consistent Listing: GCS guarantees strong consistency for both object and bucket listing operations.
GetCommitsResponse	Response container for CommitCoordinatorClient.getCommits(TableDescriptor, Long, Long).
HadoopFileSystemLogStore	Default implementation of LogStore for Hadoop FileSystem implementations.
HDFSLogStore	The LogStore implementation for HDFS, which uses Hadoop FileContext API's to provide the necessary atomic and durability guarantees: Atomic visibility of files: `FileContext.rename` is used write files which is atomic for HDFS. Consistent file listing: HDFS file listing is consistent.
IcebergMetadata	Metadata for Delta Uniform Iceberg conversion.
InvalidTargetTableException	This exception is thrown by the UC client in case a commit attempt tried to add a UUID-based commit to the wrong table.
LineCloseableIterator	Turn a Reader to CloseableIterator which can be read on demand.
LocalLogStore	Default LogStore implementation (should be used for testing only!).
LogStore	:: DeveloperApi ::
LogStoreErrors
PathLock	A lock that provides per-file-path `acquire` and `release` semantics.
S3LogStoreUtil	Static utility methods for the S3SingleDriverLogStore.
S3SingleDriverLogStore	Single JVM LogStore implementation for S3.
TableDescriptor	Container for all the info to uniquely identify the table
TableIdentifier	Identifier for a table.
ThreadUtils
UCClient	Interface for interacting with the Unity Catalog.
UCClient.ColumnDef	Column definition for registering table schema with Unity Catalog.
UCCommitCoordinatorClient	A commit coordinator client that uses unity-catalog as the commit coordinator.
UCCommitCoordinatorException	Base class for all exceptions thrown by the UC client from coordinated commits-related APIs.
UCCoordinatedCommitsUsageLogs	Class containing usage logs emitted by Coordinated Commits.
UCTokenBasedRestClient	A REST client implementation of UCClient for interacting with Unity Catalog's commit coordination service.
UniformMetadata	Metadata for Delta Universal Format (UniForm) conversions.
UpdatedActions	A container class to inform the CommitCoordinatorClient about any changes in Protocol/Metadata
UpgradeNotAllowedException	This exception is thrown by the UC client in case the client attempted an upgrade of a table to a UC managed table but the upgrade is not allowed because the previous commit was a downgrade.
