Package	Description
com.bigdata.journal	The journal is an append-only persistence capable data structure supporting atomic commit, named indices, and transactions.
com.bigdata.mdi	This package provides a metadata index and range partitioned indices managed by that metadata index.
com.bigdata.rdf.spo	This package defines a statement model using long term identifiers rather than RDF Value objects.
com.bigdata.resources	This package provides the logic to managed the live journal and the historical journals and index segments for a DataService.
com.bigdata.service	This package provides implementations of bigdata services (metadata service, data service, transaction manager service.

Class and Description
ResourceManager The ResourceManager has broad responsibility for journal files, index segment files, maintaining index views during overflow processing, and managing the transparent decomposition of scale-out indices and the distribution of the key-range index partitions for those scale-out indices.

Class and Description
AbstractTestSegSplitter Unit tests for splitting an index segment based on its size on the disk, the nominal size of an index partition, and an optional application level constraint on the choice of the separator keys.

Class and Description
AbstractAtomicUpdateTask Abstract base class for tasks responsible for the atomic update of the view of an index partition.
AbstractPrepareTask Base class for the prepare phase which reads on the old journal.
AbstractResourceManagerBootstrapTestCase
AbstractResourceManagerTask Abstract base class for tasks run during post-processing of a journal by the ResourceManager.
AbstractResourceManagerTestCase Base class for ResourceManager test suites that can use normal startup and shutdown.
AbstractResourceManagerTestCase.MockMetadataService A minimal implementation of IMetadataService - only those methods actually used by the ResourceManager are implemented.
AbstractResult Abstract base class for results when post-processing a named index partition on the old journal after an overflow operation.
AbstractTestSegSplitter Unit tests for splitting an index segment based on its size on the disk, the nominal size of an index partition, and an optional application level constraint on the choice of the separator keys.
BuildResult The result of an CompactingMergeTask.
IndexManager Class encapsulates logic and handshaking for tracking which indices (and their backing stores) are recently and currently referenced.
IndexManager.IIndexManagerCounters Performance counters for the IndexManager.
IndexManager.Options Options understood by the IndexManager.
IndexSegmentIndex BTree mapping IndexSegmentStore createTimes to IResourceMetadata records.
IPartitionIdFactory An interface which shields callers from handling RMI exceptions and which allows the use of mock implementations when you do not really want to assign partition identifiers using the IMetadataService.nextPartitionId(String).
JoinResult The result of a JoinIndexPartitionTask.
JournalIndex BTree mapping IJournal createTimes (long integers) to JournalMetadata records describing the IJournal.
MoveResult The object returned by MoveIndexPartitionTask.
NoSuchStoreException An instance of this class is thrown when a UUID does not identify any store known to the StoreManager.
OverflowActionEnum The different actions that we can take to handle an index partition during overflow processing.
OverflowCounters Utility class exposes some counter values while protecting the actual counters on the service from modification.
OverflowManager Class encapsulates logic for handling journal overflow events.
OverflowManager.IOverflowManagerCounters Performance counters for the OverflowManager.
OverflowManager.Options Options understood by the OverflowManager.
OverflowMetadata Metadata on the entire synchronous and asynchronous overflow task.
OverflowSubtaskEnum Various kinds of subtasks for asynchronous index partition overflow tasks.
PurgeResult A class that captures the results of StoreManager.purgeOldResources().
ResourceEvents Class encapsulates reporting API for resource (index and store files) events.
ResourceFileFilter The default implementation accepts directories under the configured IResourceManager.getDataDir() and files with either Options.JNL or Options.SEG file extensions.
ResourceManager The ResourceManager has broad responsibility for journal files, index segment files, maintaining index views during overflow processing, and managing the transparent decomposition of scale-out indices and the distribution of the key-range index partitions for those scale-out indices.
SplitResult The result of a SplitIndexPartitionTask including enough metadata to identify the index partitions to be created and the index partition to be deleted.
StaleLocatorReason Typesafe enumeration of the possible reasons why an index partition locator is stale.
StoreManager Class encapsulates logic for managing the store files (journals and index segments), including the logic to compute the effective release time for the managed resources and to release those resources by deleting them from the file system.
StoreManager.IStoreManagerCounters Performance counters for the StoreManager.
StoreManager.ManagedJournal The StoreManager.ManagedJournal provides the backing store used to absorb writes and retain history for the scale-out architecture.
StoreManager.Options Options for the StoreManager.
TestReleaseResources Test release (aka purge) of old resources.

Class and Description
StaleLocatorException An instance of this class is thrown when an index partition has been split, joined, or moved to indicate that the client has a stale PartitionLocator and should refresh the locator for the key range covered by the named index partition and retry their request on the appropriate DataService.
