Fields§

§pinned_checkpoints: Vec<(CheckpointSequenceNumber, CheckpointDigest)>

List of “known-good” checkpoints that state sync will be forced to use. State sync will skip verification of pinned checkpoints, and reject checkpoints with digests that don’t match pinned values for a given sequence number.

This can be used:

  • in case of a fork, to prevent the node from syncing to the wrong chain.
  • in case of a network stall, to force the node to proceed with a manually-injected checkpoint.
§interval_period_ms: Option<u64>

Query peers for their latest checkpoint every interval period.

If unspecified, this will default to 5,000 milliseconds.

§mailbox_capacity: Option<usize>

Size of the StateSync actor’s mailbox.

If unspecified, this will default to 1,024.

§synced_checkpoint_broadcast_channel_capacity: Option<usize>

Size of the broadcast channel use for notifying other systems of newly sync’ed checkpoints.

If unspecified, this will default to 1,024.

§checkpoint_header_download_concurrency: Option<usize>

Set the upper bound on the number of checkpoint headers to be downloaded concurrently.

If unspecified, this will default to 400.

§checkpoint_content_download_concurrency: Option<usize>

Set the upper bound on the number of checkpoint contents to be downloaded concurrently.

If unspecified, this will default to 400.

§checkpoint_content_download_tx_concurrency: Option<u64>

Set the upper bound on the number of individual transactions contained in checkpoint contents to be downloaded concurrently. If both this value and checkpoint_content_download_concurrency are set, the lower of the two will apply.

If unspecified, this will default to 50,000.

§timeout_ms: Option<u64>

Set the timeout that should be used when sending most state-sync RPC requests.

If unspecified, this will default to 10,000 milliseconds.

§checkpoint_content_timeout_ms: Option<u64>

Set the timeout that should be used when sending RPC requests to sync checkpoint contents.

If unspecified, this will default to 10,000 milliseconds.

§push_checkpoint_summary_rate_limit: Option<NonZeroU32>

Per-peer rate-limit (in requests/sec) for the PushCheckpointSummary RPC.

If unspecified, this will default to no limit.

§get_checkpoint_summary_rate_limit: Option<NonZeroU32>

Per-peer rate-limit (in requests/sec) for the GetCheckpointSummary RPC.

If unspecified, this will default to no limit.

§get_checkpoint_contents_rate_limit: Option<NonZeroU32>

Per-peer rate-limit (in requests/sec) for the GetCheckpointContents RPC.

If unspecified, this will default to no limit.

§get_checkpoint_contents_inflight_limit: Option<usize>

Per-peer inflight limit for the GetCheckpointContents RPC.

If unspecified, this will default to no limit.

§get_checkpoint_contents_per_checkpoint_limit: Option<usize>

Per-checkpoint inflight limit for the GetCheckpointContents RPC. This is enforced globally across all peers.

If unspecified, this will default to no limit.

§wait_interval_when_no_peer_to_sync_content_ms: Option<u64>

The amount of time to wait before retry if there are no peers to sync content from. If unspecified, this will set to default value
