Network tuning parameters. This is serialized carefully so all the values can be represented as strings in YAML - and we will be able to proceed with a printed warning for tuning params that are removed, but still specified in configs.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

gossip_strategy: String

Gossip strategy to use. [Default: “sharded-gossip”]

gossip_loop_iteration_delay_ms: u32

Delay between gossip loop iteration. [Default: 1s]

gossip_outbound_target_mbps: f64

The gossip loop will attempt to rate-limit output to this count mega bits per second. [Default: 0.5]

gossip_inbound_target_mbps: f64

The gossip loop will attempt to rate-limit input to this count mega bits per second. [Default: 0.5]

gossip_historic_outbound_target_mbps: f64

The gossip loop will attempt to rate-limit outbound traffic for the historic loop (if there is one) to this count mega bits per second. [Default: 0.1]

gossip_historic_inbound_target_mbps: f64

The gossip loop will attempt to rate-limit inbound traffic for the historic loop (if there is one) to this count mega bits per second. [Default: 0.1]

gossip_peer_on_success_next_gossip_delay_ms: u32

How long should we hold off talking to a peer we’ve previously spoken successfully to. [Default: 1 minute]

gossip_peer_on_error_next_gossip_delay_ms: u32

How long should we hold off talking to a peer we’ve previously gotten errors speaking to. [Default: 5 minute]

gossip_agent_info_update_interval_ms: u32

How often should we update and publish our agent info? [Default: 5 minutes]

gossip_local_sync_delay_ms: u32

How frequently we should locally sync when there is no new data. Agents arc can change so this shouldn’t be too long. [Default: 1 minutes]

gossip_redundancy_target: f64

The target redundancy is the number of peers we expect to hold any given Op.

gossip_max_batch_size: u32

The max number of bytes of op data to send in a single message. Payloads larger than this are split into multiple batches.

gossip_dynamic_arcs: bool

Should gossip dynamically resize storage arcs?

gossip_single_storage_arc_per_space: bool

Allow only the first agent to join the space to have a sized storage arc. [Default: false] This is an experimental feature that sets the first agent to join as the full arc and all other later agents to empty. It should not be used in production unless you understand what you are doing.

default_rpc_single_timeout_ms: u32

Default timeout for rpc single. [Default: 30s]

default_rpc_multi_remote_agent_count: u8

Default agent count for rpc multi. [Default: 3]

default_rpc_multi_remote_request_grace_ms: u64

Default remote request grace ms. [Default: 3s] If we already have results from other sources, but made any additional outgoing remote requests, we’ll wait at least this long for additional responses.

agent_info_expires_after_ms: u32

Default agent expires after milliseconds. [Default: 20 minutes]

tls_in_mem_session_storage: u32

Tls in-memory session storage capacity. [Default: 512]

proxy_keepalive_ms: u32

How often should NAT nodes refresh their proxy contract? [Default: 2 minutes]

proxy_to_expire_ms: u32

How often should proxy nodes prune their ProxyTo list? Note - to function this should be > proxy_keepalive_ms. [Default: 5 minutes]

concurrent_limit_per_thread: usize

Mainly used as the for_each_concurrent limit, this restricts the number of active polled futures on a single thread. [Default: 4096]

tx2_quic_max_idle_timeout_ms: u32

tx2 quic max_idle_timeout [Default: 30 seconds]

tx2_pool_max_connection_count: usize

tx2 pool max connection count [Default: 4096]

tx2_channel_count_per_connection: usize

tx2 channel count per connection [Default: 2]

tx2_implicit_timeout_ms: u32

tx2 timeout used for passive background operations like reads / responds. [Default: 30 seconds]

tx2_initial_connect_retry_delay_ms: usize

tx2 initial connect retry delay (note, this delay is currenty exponentially backed off– multiplied by 2x on every loop) [Default: 200 ms]

danger_tls_keylog: String

if you would like to be able to use an external tool to debug the QUIC messages sent and received by kitsune you’ll need the decryption keys. The default of "no_keylog" is secure and will not write any keys Setting this to "env_keylog" will write to a keylog specified by the SSLKEYLOGFILE environment variable, or do nothing if it is not set, or is not writable.

danger_gossip_recent_threshold_secs: u64

Set the cutoff time when gossip switches over from recent to historical gossip. This is dangerous, because gossip may not be possible with nodes using a different setting for this threshold. Do not change this except in testing environments. [Default: 15 minutes]

disable_publish: bool

Don’t publish ops, only rely on gossip. Useful for testing the efficacy of gossip.
