RabbitMQ 3.7.0 Milestone 7 发布了,RabbitMQ 是由 LShift 提供的一个 Advanced Message Queuing Protocol (AMQP) 的开源实现,由以高性能、健壮以及可伸缩性出名的 Erlang 写成,因此也是继承了这些优点。

这是一个预计将于 2017 年上半年发布的预览功能版本。部分更新内容如下:

突破性变化

服务器端

增强

  • New configuration file format

    RabbitMQ now supports a new configuration file format.
    The format is based on sysctl
    and is similar to .ini files. Erlang term configuration files are still supported, it is also
    possible to combine the two formats (use both rabbitmq.conf and advanced.config).

    Most documentation examples were updated to use both new and classic config formats. See the docs
    at next.rabbitmq.com, in particular the configuration guide,
    for more information.

    GitHub issue: rabbitmq-server#550

  • Pluggable cluster peer discovery

    Automatic clustering for blank (without an existing database) nodes now can discover
    peers using a pluggable backend. This is a feature borrowed from the rabbitmq-autocluster plugin
    by Gavin Roy.

    GitHub issue: rabbitmq-server#486

  • Nodes in a cluster now can be restared in arbitrary order. They will attempt to contact
    one of the previously seen peers periodically (10 times with 30 second intervals by default).

    GitHub issue: rabbitmq-server#1022

  • Support config file path values with and without file extensions

    RabbitMQ no longer requires RABBITMQ_CONFIG_FILE values to not have a .config or .conf suffix. It will try appending both suffixes as needed when searching for suitable config file(s) to load.

    Github Issue: rabbitmq-server#691

  • Operators now can configure how many concurrent connections are allowed in a vhost.

    GitHub issue: rabbitmq-server#500

  • Operators now can configure how many queues can exist in a vhost.

    GitHub issue: rabbitmq-server#501

  • Operator policies: their definitions are merged with the standard (user) policies and allow operators put global
    limits in place, e.g. max queue length or message TTL.

    GitHub issue: rabbitmq-server#930

  • Plugin version constraints

    RabbitMQ now has a mechanism for plugin authors to indicate what versions a plugin is compatible with. Incompatible plugins are logged and ignored.

    Github Issue: rabbitmq-server#591,
    rabbitmq-server#735

  • Lager-based logging: pluggable backends, debug log level, more flexibility in
    configuration.

    RabbitMQ now uses Lager for its logging subsystem.
    This brings a group of benefits: (quite verbose) debug log level, pluggable logging
    backends (e.g. logging to Syslog no longer requires external tools), and much
    more flexibility in logging configuration.

    See rabbitmq.config.example
    for examples of logging configuration with Lager.

    GitHub issue: rabbitmq-server#94

  • Deleting a vhost now will force close all connections in it.

    GitHub issue: rabbitmq-server#627

  • LF and CR are now stripped off of names of queues and exchanges

    Although line feeds in names are permitted under the AMQP 0-9-1 spec, in practice they can make it very difficult to work with queues and exchanges. Stripping them out makes life much easier for developers.

    Github issue: rabbitmq-server#710

  • Deletion of auto-delete and exclusive queues now leaves (debug) log entries

    GitHub issue: rabbitmq-server#590

Bug 修复

  • Mirrored queue could terminate if a policy is re-applied concurrently after promotion

    GitHub issue: rabbitmq-server#803

  • Old incarnations of queue mirrors are stopped before new ones start

    GitHub issue: rabbitmq-server#863

  • Channel interceptors are enabled/disabled together with plugins

    GitHub issue: rabbitmq-server#559
