Class used to push numbers about WAL edits replay into the metrics subsystem.
|
MetricsWALSourceImpl |
Class that transitions metrics from MetricsWAL into the metrics subsystem.
|
ProtobufLogReader |
A Protobuf based WAL has the following structure:
|
ProtobufLogWriter |
Writer for protobuf-based WAL.
|
ReaderBase | |

A WALCellCodec that encrypts the WALedits.
|
SequenceFileLogReader | |
SequenceFileLogWriter |
Implementation of
WALProvider.Writer that delegates to
SequenceFile.Writer. |
TestCompressor |

TestKeyValueCompression | |
TestLogRollAbort |
Tests for conditions that should trigger RegionServer aborts when
rolling the current WAL fails.
|
TestLogRolling |
Test log deletion as logs are rolled.
|
TestLogRollingNoCluster |
Test many concurrent appenders to an
#WAL while rolling the log. |

Test replay of edits out of a WAL split.
|
TestWALReplay.CustomStoreFlusher | |
TestWALReplayCompressed |
Enables compression and runs the TestWALReplay tests.
|
WALActionsListener.Base | |
WALCellCodec |
Compression in this class is lifted off Compressor/KeyValueCompression.

WALCellCodec.EnsureKvEncoder | |
WALCoprocessorHost |
Implements the coprocessor environment and runtime support for coprocessors
loaded within a
WAL . |
WALEdit |
WALEdit: Used in HBase's transaction log (WAL) to represent
the collection of edits (KeyValue objects) corresponding to a
single transaction.
|
WALEditsReplaySink |
This class is responsible for replaying the edits coming from a failed region server.
|
WALUtil |
Helper methods to ease Region Server integration with the write ahead log.
