TransactionAware	Interface to be implemented by a component that interacts with transaction logic.
TransactionExecutor	Utility that wraps the execution of a function into the context of a transaction.
TransactionExecutor.Function<I,O>	A function is a class with a single method that takes an argument and returns a result.
TransactionExecutor.Procedure<I>	A procedure is a class with a single void method that takes an argument.
TransactionExecutor.Subroutine	A subroutine is a class with a single void method without arguments.
TransactionExecutorFactory	A factory for transaction executors.
TransactionSystemClient	Client talking to transaction system.

Class Summary

Class	Description
AbstractTransactionAwareTable	Base class for all the common parts of the HBase version-specific TransactionAwareHTable implementations.
AbstractTransactionExecutor	Provides implementation of asynchronous methods of TransactionExecutor by delegating their execution to respective synchronous methods via provided ExecutorService.
ChangeId	Represents a row key from a data set changed as part of a transaction.
DefaultTransactionExecutor	Utility class that encapsulates the transaction life cycle over a given set of transaction-aware datasets.
NoRetryStrategy	Does no retries
RetryOnConflictStrategy	Retries transaction execution when transaction fails with TransactionConflictException.
RetryStrategies	Collection of RetryStrategys.
Transaction	Transaction details
TransactionAdmin	Allows calling some methods on TransactionManager from command line.
TransactionAwares	Utility class that provides handy methods for working with TransactionAware classes and their instances.
TransactionCodec	Handles serialization and deserialization of Transaction instances to and from byte[].
TransactionContext	Utility class that encapsulates the transaction life cycle over a given set of transaction-aware datasets.
TransactionManager	This is the central place to manage all active transactions in the system.
TransactionManager.ChangeSet	Represents a set of changes from a client.
TransactionManager.InProgressTx	Represents some of the info on in-progress tx
TransactionServiceMain	Driver class to start and stop tx in distributed mode.
TxConstants	Transaction system constants
TxConstants.HBase	Configuration properties used by HBase
TxConstants.Manager	TransactionManager configuration.
TxConstants.Metrics	Configuration properties for metrics reporting
TxConstants.Persist	Configuration for the transaction snapshot persistence.
TxConstants.Service	TransactionService configuration.
TxConstants.TransactionLog	Configuration for transaction log edit entries
TxConstants.TransactionPruning	Configuration for invalid transaction pruning

Enum Summary

Enum	Description
Transaction.VisibilityLevel	Defines the possible visibility levels for read operations.
TransactionManager.InProgressType	Type of in-progress transaction.
TransactionType	Type of transaction.
TxConstants.ConflictDetection	Defines what level of conflict detection should be used for transactions.

Exception Summary

Exception	Description
InvalidTruncateTimeException	Thrown when truncate invalid list is called with a time, and when there are in-progress transactions that were started before the given time.
TransactionConflictException	Thrown to indicate transaction conflict occurred when trying to commit a transaction.
TransactionCouldNotTakeSnapshotException	Throw when taking a snapshot fails.
TransactionFailureException	Thrown to indicate execution of a transaction failed.
TransactionNotInProgressException	Thrown when transaction has timed out.
TransactionSizeException	Thrown to indicate that a transaction's change set exceeds the allowed size.
