All Classes and Interfaces

Class	Description
AbstractCommitInfo	Interface for objects that represents the base information for a commit.
AbstractDomainMetadata	Interface for Delta domain-metadata actions.
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
CommitCompletionUnknownException	Raised when UC cannot determine whether the commit at the requested version already landed: the version is at or below the latest commit, but UC retains no row at it (the row was backfilled and cleaned up), so UC cannot tell whether the version holds this caller's own commit or a different writer's.
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
CredentialFetchFailedException	Thrown by UCDeltaClient when credential vending exhausts retries.
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
NoSuchTableException	Thrown by UCDeltaClient operations when the catalog reports that the requested table does not exist (HTTP 404).
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.
UCConfigUtils	Shared utility methods for parsing flat UC configuration maps (e.g.
UCCoordinatedCommitsUsageLogs	Class containing usage logs emitted by Coordinated Commits.
UCDeltaClient	Extends UCClient with Delta table lifecycle operations backed by the UC Delta API (load, stage, and create tables).
UCDeltaGetCommitsResponse	Extended response for CommitCoordinatorClient.getCommits(io.delta.storage.commit.TableDescriptor, java.lang.Long, java.lang.Long) implementations backed by the Delta REST loadTable API.
UCDeltaModels	Delta-owned models for the UC Delta API.
UCDeltaModels.CommitReport	Per-commit metrics payload reported to Unity Catalog.
UCDeltaModels.DeltaProtocol
UCDeltaModels.FileSizeHistogram	Post-commit file-size distribution snapshot, reported alongside the commit report.
UCDeltaModels.StagingTableInfo
UCDeltaModels.TableInfo	Result of UCDeltaClient.loadTable(io.delta.storage.commit.TableIdentifier) / UCDeltaClient.createTable(java.net.URI, io.delta.storage.commit.TableIdentifier, io.delta.storage.commit.uccommitcoordinator.UCDeltaModels.TableType, io.delta.storage.commit.actions.AbstractMetadata, io.delta.storage.commit.actions.AbstractProtocol, java.util.List<io.delta.storage.commit.actions.AbstractDomainMetadata>, long, java.util.Optional<io.delta.storage.commit.uniform.UniformMetadata>).
UCDeltaModels.TableType
UCDeltaTokenBasedRestClient	A REST client implementation of UCDeltaClient that uses the UC Delta API for all table lifecycle and commit coordination operations.
UCTokenBasedRestClient	A REST client implementation of UCClient for interacting with Unity Catalog's commit coordination service.
UniformMetadata	Metadata for Delta Universal Format (UniForm) conversions.
UnsupportedTableFormatException	Thrown when the catalog refuses to serve a non-Delta table.
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.
