WalReader
public static record WalReader.WalRecoveryMetadata(List<LogEntry> entries, long lastValidIndex, int totalEntriesRecovered, int corruptedEntriesSkipped, long corruptionPosition) extends Record
Recovery metadata returned after reading a WAL file.

Contains the recovered log entries and statistics useful for diagnostics: - entries: list of successfully recovered LogEntry objects - lastValidIndex: the index of the last valid entry in the WAL (0 if no valid entries) - totalEntriesRecovered: count of successfully recovered entries - corruptedEntriesSkipped: count of corrupted entries skipped - corruptionPosition: byte offset of the first corruption, or -1 if no corruption

    • WalRecoveryMetadata

      public WalRecoveryMetadata(List<LogEntry> entries, long lastValidIndex, int totalEntriesRecovered, int corruptedEntriesSkipped, long corruptionPosition)
      Creates an instance of a WalRecoveryMetadata record class.
      Parameters:
      entries - the value for the entries record component
      lastValidIndex - the value for the lastValidIndex record component
      totalEntriesRecovered - the value for the totalEntriesRecovered record component
      corruptedEntriesSkipped - the value for the corruptedEntriesSkipped record component
      corruptionPosition - the value for the corruptionPosition record component

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
