public interface WriteRequestsLogger
Write-side request logging hooks used by SBK loggers. Implementations can optionally aggregate per-writer metrics (counts, bytes, timeouts) to be emitted periodically or exported to external systems.

  • Method Details

    • recordWriteRequests

      void recordWriteRequests(int writerId, long startTime, long bytes, long events)
      Record one or more write requests attributed to a writer.
      Parameters:
      writerId - logical writer identifier (0..N-1)
      startTime - write start time in the active TimeUnit
      bytes - bytes written for these events
      events - number of write events

    • recordWriteTimeoutEvents

      void recordWriteTimeoutEvents(int writerId, long startTime, long timeoutEvents)
      Record write timeout events for a writer.
      Parameters:
      writerId - logical writer identifier (0..N-1)
      startTime - time when timeouts were observed
      timeoutEvents - number of timeout events

    • getMaxWriterIDs

      int getMaxWriterIDs()
      Maximum number of writer IDs the logger expects to track. Returning 0 disables per-writer request logging.
      Returns:
      max writer IDs
