Sidekiq Pro Changelog

Please see http://sidekiq.org/pro for more details and how to buy.

1.2.2

• Problem with reliable fetch which could lead to lost jobs when Sidekiq is shut down normally. Thanks to MikaelAmborn for the report. [#1109]

1.2.1

• Forgot to push paging code necessary for delete_job performance.

1.2.0

• LEAK Fix batch key which didn't expire in Redis. Keys match /b-[a-f0-9]{16}-pending/, e.g. "b-4f55163ddba10aa0-pending" [#1057]
• Reliable fetch now supports multiple queues, using the algorithm spec'd by @jackrg [#1102]
• Fix issue with reliable_push where it didn't return the JID for a pushed job when sending previously cached jobs to Redis.
• Add fast Sidekiq::Queue#delete_job(jid) API which leverages Lua so job lookup is 100% server-side. Benchmark vs Sidekiq's Job#delete API:

Sidekiq Pro API
  0.030000   0.020000   0.050000 (  1.640659)
Sidekiq API
 17.250000   2.220000  19.470000 ( 22.193300)

• Add fast Sidekiq::Queue#delete_by_class(klass) API to remove all jobs of a given type. Uses server-side Lua for performance.

1.1.0

• New sidekiq/pro/reliable_push which makes Sidekiq::Client resiliant to Redis network failures. [#793]
• Move sidekiq/reliable_fetch to sidekiq/pro/reliable_fetch

1.0.0

• Sidekiq Pro changelog moved to mperham/sidekiq for public visibility.
• Add new Rack endpoint for easy polling of batch status via JavaScript. See sidekiq/rack/batch_status

0.9.3

• Fix bad /batches path in Web UI
• Fix Sinatra conflict with sidekiq-failures

0.9.2

• Fix issue with lifecycle notifications not firing.

0.9.1

• Update due to Sidekiq API changes.

0.9.0

• Rearchitect Sidekiq's Fetch code to support different fetch strategies. Add a ReliableFetch strategy which works with Redis' RPOPLPUSH to ensure we don't lose messages, even when the Sidekiq process crashes unexpectedly. [mperham/sidekiq#607]

0.8.2

• Reimplement existing notifications using batch on_complete events.

0.8.1

• Rejigger batch callback notifications.

0.8.0

• Add new Batch 'callback' notification support, for in-process notification.
• Symbolize option keys passed to Pony [mperham/sidekiq#603]
• Batch no longer requires the Web UI since Web UI usage is optional. You must require is manually in your Web process:

require 'sidekiq/web'
require 'sidekiq/batch/web'
mount Sidekiq::Web => '/sidekiq'

0.7.1

• Worker instances can access the associated jid and bid via simple accessors.
• Batches can now be modified while being processed so, e.g. a batch job can add additional jobs to its own batch.

def perform(...)
  batch = Sidekiq::Batch.new(bid) # instantiate batch associated with this job
  batch.jobs do
    SomeWorker.perform_async # add another job
  end
end

• Save error backtraces in batch's failure info for display in Web UI.
• Clean up email notification a bit.

0.7.0

• Add optional batch description
• Mutable batches. Batches can now be modified to add additional jobs at runtime. Example would be a batch job which needs to create more jobs based on the data it is processing.

batch = Sidekiq::Batch.new(bid)
batch.jobs do
  # define more jobs here
end

• Fix issues with symbols vs strings in option hashes

0.6.1

• Webhook notification support

0.6

• Redis pubsub
• Email polish

0.5

• Batches
• Notifications
• Statsd middleware
