Protocol v4.1.4

on GitHub

This release updates full node grpc streaming.

• Introduces a configurable protocol-side buffered channel of full node streaming updates.

  • prevents the full node from halting/lagging on a slow or unresponsive client by buffering updates.
  • Once the configurable buffer limit is reached, all subscriptions and buffered updates will be dropped.

• The grpc-streaming-buffer-size CLI flag has been added.

  • Defaults to 1000. Please adjust based on the responsiveness of your client implementation.

• Metrics emitted

  • Buffer size is emitted as a gauge (grpc_streaming_buffer_size)
  • Number connections is emitted as a gauge (grpc_streaming_num_connections)

Note that the grpc streaming proto changes from v4.1.3 to v4.1.4 are proto-compatible. Current grpc streaming clients will not need to be updated.
