  # Timeout for bootstrap control
  #
  # An Olric node checks operation status before taking any action for the
  # cluster events, responding incoming requests and running API functions.
  # Bootstrapping status is one of the most important checkpoints for an
  # "operable" Olric node. BootstrapTimeout sets a deadline to check
  # bootstrapping status without blocking indefinitely.
  bootstrapTimeout: 5s

  # Coordinator member pushes the routing table to cluster members in the case of

  # Olric can send push cluster events to cluster.events channel. Available cluster events:
  #
  # * node-join-event
  # * node-left-event
  # * fragment-migration-event

  # If you want to receive these events, set true to EnableClusterEventsChannel and subscribe to
  # cluster.events channel. Default is false.
  enableClusterEventsChannel: true

client:
  # Timeout for TCP dial.
  #
  # The timeout includes name resolution, if required. When using TCP, and the host in the address parameter
  # resolves to multiple IP addresses, the timeout is spread over each consecutive dial, such that each is
  # given an appropriate fraction of the time to connect.
  dialTimeout: 5s

  # Timeout for socket reads. If reached, commands will fail
  # with a timeout instead of blocking. Use value -1 for no timeout and 0 for default.

  # Timeout for socket writes. If reached, commands will fail
  # with a timeout instead of blocking.
  # Default is DefaultWriteTimeout
  writeTimeout: 3s

  # Maximum number of retries before giving up.
  # Default is 3 retries; -1 (not 0) disables retries.
  #maxRetries: 3

  # Minimum backoff between each retry.
  # Default is 8 milliseconds; -1 disables backoff.
  #minRetryBackoff: 8ms

  # Maximum backoff between each retry.
  # Default is 512 milliseconds; -1 disables backoff.

  # Minimum number of idle connections which is useful when establishing
  # new connection is slow.
  #minIdleConns:

  # Connection age at which client retires (closes) the connection.
  # Default is to not close aged connections.
  #maxConnAge:

  # Amount of time client waits for connection if all connections are busy before
  # returning an error. Default is ReadTimeout + 1 second.
  #poolTimeout: 3s

  # Amount of time after which client closes idle connections.
  # Should be less than server's timeout.
  # Default is 5 minutes. -1 disables idle timeout check.
  idleTimeout: 5m

  # Frequency of idle checks made by idle connections reaper.
  # Default is 1 minute. -1 disables idle connections reaper,
  # but idle connections are still discarded by the client
  # if IdleTimeout is set.
  idleCheckFrequency: 1m


logging:
  # DefaultLogVerbosity denotes default log verbosity level.
  #
  # * 1 - Generally useful for this to ALWAYS be visible to an operator
  #   * Programmer errors
  #   * Logging extra info about a panic
  #   * CLI argument handling
  # * 2 - A reasonable default log level if you don't want verbosity.
  #   * Information about config (listening on X, watching Y)
  #   * Errors that repeat frequently that relate to conditions that can be
  #     corrected
  # * 3 - Useful steady state information about the service and
  #     important log messages that may correlate to
  #   significant changes in the system.  This is the recommended default log
  #     level for most systems.
  #   * Logging HTTP requests and their exit code
  #   * System state changing
  #   * Controller state change events
  #   * Scheduler log messages
  # * 4 - Extended information about changes
  #   * More info about system state changes
  # * 5 - Debug level verbosity
  #   * Logging in particularly thorny parts of code where you may want to come
  #     back later and check it
  # * 6 - Trace level verbosity
  #   * Context to understand the steps leading up to neterrors and warnings
  #   * More information for troubleshooting reported issues
  verbosity: 3

  # Default LogLevel is DEBUG. Available levels: "DEBUG", "WARN", "ERROR", "INFO"
