sidekiq-statistic: The gem does not scale

We deployed this gem on a fairly busy sidekiq app. It wound up shooting our memory usage up to 1.9 GB after 3 weeks. After removing sidekiq-statistic and all of the large-sized :timeslist stores, it brought our memory usage down to under 30 MB. I’m not sure if there is a solution for this, maybe limiting the data that can be retrieved over time, however it should be known that sidekiq-statistic is definitely not suitable for high usage apps.
