# Welcome to Sidekiq Pro 3.0!
|
||
|
|
||
|
Sidekiq Pro 3.0 is designed to work with Sidekiq 4.0.
|
||
|
|
||
|
## What's New
|
||
|
|
||
|
* **Redis 2.8.0 or greater is required.** Redis 2.8 was released two years
|
||
|
ago and contains **many** useful features which Sidekiq couldn't
|
||
|
leverage until now. **Redis 3.0.3 or greater is recommended** for large
|
||
|
scale use.
|
||
|
|
||
|
* Sidekiq Pro no longer uses Celluloid. If your application code uses Celluloid,
|
||
|
you will need to pull it in yourself.
|
||
|
|
||
|
* Pausing and unpausing queues is now instantaneous, no more polling!
|
||
|
|
||
|
* Reliable fetch has been re-implemented due to the fetch changes in
|
||
|
Sidekiq 4.0.
|
||
|
|
||
|
* Support for platforms without persistent hostnames. Since reliable fetch
|
||
|
normally requires a persistent hostname, you may disable hostname usage on
|
||
|
platforms like Heroku and Docker:
|
||
|
```ruby
|
||
|
Sidekiq.configure_server do |config|
|
||
|
config.options[:ephemeral_hostname] = true
|
||
|
config.reliable_fetch!
|
||
|
end
|
||
|
```
|
||
|
This option is enabled automatically if Heroku's DYNO environment variable is present.
|
||
|
Without a persistent hostname, each Sidekiq process **must** have its own unique index.
|
||
|
|
||
|
* The old 'sidekiq/notifications' features have been removed.
|
||
|
|
||
|
## Upgrade
|
||
|
|
||
|
First, make sure you are using Redis 2.8 or greater. Next:
|
||
|
|
||
|
* Upgrade to the latest Sidekiq Pro 2.x.
|
||
|
```ruby
|
||
|
gem 'sidekiq-pro', '< 3'
|
||
|
```
|
||
|
* Fix any deprecation warnings you see.
|
||
|
* Upgrade to 3.x.
|
||
|
```ruby
|
||
|
gem 'sidekiq-pro', '< 4'
|
||
|
```
