  # Live collector configuration
  live:
    # Rate limit of requests/second to the Kubernetes API
    # NOTE: most (>90%) of the current runtime of KubeHound is spent in the transfer of data from the remote K8s API server,
    # and the bulk of that is spent waiting on rate limit. As such increasing this will improve performance roughly linearly.
    rate_limit_per_second: 60

    # # Number of entries retrieved by each call on the API (same for all Kubernetes entry types)
    # page_size: 500

    # # Number of pages to buffer
    # page_buffer_size: 10

  # Uncomment to use the file collector
  # type: file-collector

  # File collector configuration

  #   # Directory holding the K8s json data files
  #   directory: /path/to/directory

#
# Graph builder configuration
#
# NOTE: increasing batch sizes can have some performance improvements by reducing network latency in transferring data
# between KubeGraph and the application. However, increasing it past a certain level can overload the backend leading 
# to instability and eventually exceed the size limits of the websocket buffer used to transfer the data. Changing this
# is not recommended.
