any plans to support the new rabbitMQ stream plugin with RabbitMQ 3.9?

[alilland]

It looks like RabbitMQ has released a feature this year allowing users to create streams with RabbitMQ

https://www.rabbitmq.com/stream.html

I was looking to see if I could get it configured in ruby after installing the plugin to RabbitMQ - it runs on port 5552 according to the docs

this was my attempt, but it throws an error

# rake task
namespace :other do
  task :streaming do
    conn = Bunny.new("amqp://#{ENV['RABBITMQ_USER']}:#{ENV['RABBITMQ_PASS']}@#{ENV['RABBITMQ_HOST']}", client_properties: { connection_name: :stream })
    conn.start
    channel = conn.create_channel
    exchange = Bunny::Exchange.new(channel, :stream, 'stream')
  end
end

You can still use Streams, just not the stream protocol with Bunny, but that's optional. Just set x-queue-type to "stream", see more here: https://www.rabbitmq.com/streams.html

[alilland]

unfortunately it still throws the same error with x-queue-type

 ch = conn.create_channel
stream = ch.queue('stream_test', durable: true, auto_delete: false, arguments: { 'x-queue-type': 'stream', 'x-max-length-bytes': 500_000_000 })

It's because you try to connect to the wrong port, use port 5672, not 5552

No plans. Stream protocol support should be implemented a separate client. You can use basic operations on streams using Bunny but won't get must of the benefits.

For every other language that has a RabbitMQ Stream Protocol client, it was a completely brand new library and not an extension to the existing client.
