Keep history of jobs executed for more than 1 day in Hangfire

问题

I've just started using Hangfire, and I am loving it.

I understand that Hangfire maintains the history for succeeded jobs for 1 day, and clear it thereafter.

Is there is a way where I can customize this default behavior and persist the history for any duration say 7 days?

To do this, you need to create a job filter and register it through hangfire global configurations, as discussed here - https://discuss.hangfire.io/t/how-to-configure-the-retention-time-of-job/34

Create job filter -

using Hangfire.Common;
using Hangfire.States;
using Hangfire.Storage;
using System;

namespace HangfireDemo
{
    public class ProlongExpirationTimeAttribute : JobFilterAttribute, IApplyStateFilter
    {
        public void OnStateApplied(ApplyStateContext filterContext, IWriteOnlyTransaction transaction)
        {
            filterContext.JobExpirationTimeout = TimeSpan.FromDays(7);
        }

        public void OnStateUnapplied(ApplyStateContext context, IWriteOnlyTransaction transaction)
        {
            context.JobExpirationTimeout = TimeSpan.FromDays(7);
        }
    }
}

...and register in global job filters -

GlobalJobFilters.Filters.Add(new ProlongExpirationTimeAttribute());
