1.1.0 🚸

This is a maintenance release. Most changes are internal and doesn't affect public APIs.

Changes

• Dropped deprecated AnyCable RPC v0.6 support.

• Added concurrency to broadcasting.

Now new broadcast messages are handled (and retransmitted) concurrently by a pool of workers (Go routines).
You can control the size of the pool via the hub_gopool_size configuration parameter (defaults to 16).

Features

• Added server_msg_total, failed_server_msg_total, data_sent_bytes_total and data_rcvd_bytes_total metrics.

• Added --ping_timestamp_precision option to specify ping messages timestamp precision.

• Added --allowed_origins optional configuration.

You can provide a comma-separated list of hostnames to check the Origin header against during the WebSocket Upgrade. Supports wildcards, e.g., --allowed_origins=*.evl.ms,www.evlms.io.

• Added --max-conn option.

Hard-limit the number of simultaneous connections.

v1.0.2

Bump 1.0.2

v1.0.1

Bump 1.0.1

1.0.0

Features

• AnyCable RPC 1.0 compatibility.

See the project's release notes for more information.

This release is still compatible with AnyCable RPC v0.6. The support for v0.6 is planned to be dropped in 1.1.0.

• Redis Sentinel support.

See documentation.

• New metrics:

  • mem_sys_bytes: the total bytes of memory obtained from the OS
  • rpc_retries_total: the total number of retried RPC calls (higher number could indicate incorrect concurrency configuration)

• New configuration parameters:

  • rpc_concurrency: the limit on the number of concurrent RPC calls (read documentation).
  • enable_ws_compression: enable WebSocket per-message compression (disabled by default).
  • disconnect_timeout: specify the timeout for graceful shutdown of the disconnect queue (read documentation
  • disable_disconnect: disable calling disconnect/unsubscribe callbacks.

• HTTP broadcast adapter.

See documentation.

Changes

• Docker versioning changed from vX.Y.Z to X.Y.Z for anycable-go.

Now you can specify only the part of the version, e.g. anycable-go:1.0 instead of the full anycable-go:v1.0.0.

• RPC implementation now uses a single gRPC client instead of a pool.

gRPC connection provides concurrency via H2 streams (with load balancing). Using a pool doesn't bring any performance
improvements and sometimes 'cause unstability (e.g., ResourceExhausted or Unavailable exceptions under the load).

We still limit the number of concurrent RPC requests. Now you can configure it via --rpc_concurrency setting.

See PR#88 for more.
