  • Field Summary

    Fields
    Modifier and Type
    Field
    Description
    private boolean
    closed
    If we do asynchronous close in subclasses, it is possible that when adding WALProps to the rolled map, the file is not closed yet, so in cleanOldLogs we should not archive this file, for safety.
    private final Map<byte[],Long>
    encodedName2HighestSequenceId
    Map the encoded region name to the highest sequence id.
    private final long
    logSize
    The log file size.
    private final long
    rollTimeNs
    The nanoTime of the log rolling, used to determine the time interval that has passed since.

    • encodedName2HighestSequenceId

      private final Map<byte[],Long> encodedName2HighestSequenceId
      Map the encoded region name to the highest sequence id.

      Contains all the regions it has an entry for.

    • logSize

      private final long logSize
      The log file size. Notice that the size may not be accurate if we do asynchronous close in subclasses.

    • rollTimeNs

      private final long rollTimeNs
      The nanoTime of the log rolling, used to determine the time interval that has passed since.

    • closed

      private volatile boolean closed
      If we do asynchronous close in subclasses, it is possible that when adding WALProps to the rolled map, the file is not closed yet, so in cleanOldLogs we should not archive this file, for safety.
