# Welcome to Sidekiq Pro 4.0!
|
||
|
|
|
||
|
|
Sidekiq Pro 4.0 is designed to work with Sidekiq 5.0.
|
||
|
|
|
||
|
|
## What's New
|
||
|
|
|
||
|
|
* Batches now "die" if any of their jobs die. You can enumerate the set
|
||
|
|
of dead batches and their associated dead jobs. The success callback
|
||
|
|
for a dead batch will never fire unless these jobs are fixed.
|
||
|
|
```ruby
|
||
|
|
Sidekiq::Batch::DeadSet.new.each do |status|
|
||
|
|
status.dead? # => true
|
||
|
|
status.dead_jobs # => [...]
|
||
|
|
end
|
||
|
|
```
|
||
|
|
* The older `reliable_fetch` and `timed_fetch` algorithms have been
|
||
|
|
removed. Only super\_fetch is available in 4.0.
|
||
|
|
* The statsd middleware has been tweaked to remove support for legacy,
|
||
|
|
pre-3.6.0 configuration.
|
||
|
|
|
||
|
|
## Upgrade
|
||
|
|
|
||
|
|
* Upgrade to the latest Sidekiq Pro 3.x.
|
||
|
|
```ruby
|
||
|
|
gem 'sidekiq-pro', '< 4'
|
||
|
|
```
|
||
|
|
* Fix any deprecation warnings you see.
|
||
|
|
* Upgrade to 4.x.
|
||
|
|
```ruby
|
||
|
|
gem 'sidekiq-pro', '< 5'
|
||
|
|
```
