  • Field Details

    • INITIAL_BUFFERS

      public static final int INITIAL_BUFFERS

    • MIN_BUFFERS

      public static final int MIN_BUFFERS

    • EVENT_HEAP_THRESHOLD_BYTES

      public static final long EVENT_HEAP_THRESHOLD_BYTES
      Defines the threshold (in bytes) for the total amount of heap used by the active events to prevent OutOfMemoryError. Once the active events exceed this threshold, the new ones will be truncated. Defaults to min(2G, maxMemory()/4)

    • LARGE_EVENT_THRESHOLD

      public static final int LARGE_EVENT_THRESHOLD
      Defines the length of a event that is considered large enough to account with LARGE_EVENT_TLAB_BYTES and EVENT_HEAP_THRESHOLD_BYTES. Small events will process faster as they won't require counter-bumps, however, the drawback is they would consume heap without being accounted for. Defaults to 8KiB.

    • LARGE_EVENT_TLAB_BYTES

      public static final int LARGE_EVENT_TLAB_BYTES
      Defines the size of a thread-local buffer for accounting the large event volume. Per-thread buffers reduce contention on the global counter as each thread tracks its own allocations, and it consults the global counter only if the thread-local counter reaches a threshold. Increasing the value might decrease contention EVENT_HEAP_THRESHOLD_BYTES at a cost of increasing per-thread heap consumption. Defaults to 256KiB.

    • TRUNCATED_EVENTS_THRESHOLD

      public static final int TRUNCATED_EVENTS_THRESHOLD
      Defines the number of characters kept from large events if EVENT_HEAP_THRESHOLD_BYTES is reached. Defaults to 4000

    • MAX_SCALE_ATTEMPTS

      public static final int MAX_SCALE_ATTEMPTS
