Add option to skip storing job args in status key

[ezekg]

I recently ran some diagnostics against my Sidekiq instance using RedisInsight and was shocked to see I had >1GB of data for the sidekiq:status:* keyspace. This is 10x larger than any other keyspace in my Redis database. Worth noting that I process ~1MM jobs a day that utilize sidekiq-status, and I have a status expiry of 3 days.

Upon inspection, the large keyspace was because this lib is storing the job's args for display purposes. In my case, this included potentially large JSON payloads.

I actually don't use the UI for Sidekiq, so this was needlessly wasting space and I feel like an option to disable this behavior would be beneficial for situations like this.

For now, I implemented the following monkey-patch in an initializer:

class Sidekiq::Status::ClientMiddleware
  def display_args(msg, queue)
    nil
  end
end

Thoughts?

And as an aside: for anybody else affected by this, here's a small rake task for cleaning up args for the current keyspace, to be used after applying the above monkey-patch:

# frozen_string_literal: true

desc 'clean up sidekiq-status args'
task sidekiq_status_args_cleanup: :environment do
  redis = Rails.cache.redis

  redis.with do |conn|
    conn.scan_each(match: 'sidekiq:status:*') do |key|
      puts "Clearing args: #{key}"

      conn.hdel key, :args
    end
  end
end
