Hangfire.Redis job queue is huge

I am using the latest Hangfire.Redis package and in my test environment the queue size for the Job queue is at 1596020 entries.

Is there a way to truncate this queue to reduce the Redis memory usage? I've already had to move up a tier of Azure Redis to have my app work correctly.

I have set the queue length properties in the settings, however it appears to have had no impact.
