ClassDescriptionUtility class that lets us keep track of the edit with it's key.Used in HBase's transaction log (WAL) to represent a collection of edits (Cell/KeyValue objects) that came in as a single transaction.Key for WAL Entry.A one way WAL reader, without reset and seek support.
-
ClassDescriptionRuns periodically to determine if the WAL should be rolled.A Write Ahead Log (WAL) provides service for reading, writing waledits.Entry point for users of the Write Ahead Log.

ClassDescriptionClass which accumulates edits and separates them into a buffer per region while simultaneously accounting RAM usage.A buffer of some number of edits for a given region.The following class is an abstraction class to provide a common interface to support different ways of consuming recovered edits.A Write Ahead Log (WAL) provides service for reading, writing waledits.Utility class that lets us keep track of the edit with it's key.Used in HBase's transaction log (WAL) to represent a collection of edits (Cell/KeyValue objects) that came in as a single transaction.Entry point for users of the Write Ahead Log.Key for WAL Entry.Contains some methods to control WAL-entries producer / consumer interactionsA WAL reader which is designed for be able to tailing the WAL file which is currently being written.
