| MetricsWALSource
Interface of the source that will export metrics about the region server's WAL.
|
| Class and Description |
|---|
| AbstractFSWAL
Implementation of
WAL to go against FileSystem; i.e. |
| AbstractFSWAL.WalProps |
| AbstractProtobufLogWriter
Base class for Protobuf log writer.
|
| AsyncProtobufLogWriter
AsyncWriter for protobuf-based WAL.
|
| CompressionContext
Context that holds the various dictionaries for compression in WAL.
|
| CompressionContext.DictionaryIndex |
| CompressionContext.ValueCompressor
Encapsulates the compression algorithm and its streams that we will use for value compression
in this WAL.
|
| FailedLogCloseException
Thrown when we fail close of the write-ahead-log file.
|
| FailedSyncBeforeLogCloseException
Thrown when we fail close of the write-ahead-log file.
|
| FSHLog.RingBufferEventHandler
Handler that is run by the disruptor ringbuffer consumer.
|
| FSHLog.SafePointZigZagLatch
This class is used coordinating two threads holding one thread at a 'safe point' while the
orchestrating thread does some work that requires the first thread paused: e.g.
|
| FSHLog.SyncRunner
Thread to runs the hdfs sync call.
|
| FSWALEntry
A WAL Entry for
AbstractFSWAL implementation. |
| MetricsWALSource
Interface of the source that will export metrics about the region server's WAL.
|
| ProtobufLogReader
A Protobuf based WAL has the following structure:
|
| ProtobufLogReader.WALHdrContext |
| ProtobufLogReader.WALHdrResult |
| ProtobufLogWriter
Writer for protobuf-based WAL.
|
| ReaderBase |
| RingBufferTruck
A 'truck' to carry a payload across the ring buffer from Handler to WAL.
|
| RingBufferTruck.Type |
| SequenceIdAccounting
Accounting of sequence ids per region and then by column family.
|
| SyncFuture
A Future on a filesystem sync call.
|
| SyncFutureCache
A cache of
SyncFutures. |
| WALActionsListener
Get notification of WAL events.
|
| WALActionsListener.RollRequestReason
The reason for the log roll request.
|
| WALCellCodec
Compression in this class is lifted off Compressor/KeyValueCompression.
|
| WALCellCodec.ByteStringCompressor |
| WALCellCodec.ByteStringUncompressor |
| WALCoprocessorHost
Implements the coprocessor environment and runtime support for coprocessors loaded within a
WAL. |
| WALCoprocessorHost.WALEnvironment
Encapsulation of the environment of each coprocessor
|
