How can I safely reset Hangfire to a clean state?

I've seen a pretty interesting solution here

TRUNCATE TABLE [HangFire].[AggregatedCounter]
TRUNCATE TABLE [HangFire].[Counter]
TRUNCATE TABLE [HangFire].[JobParameter]
TRUNCATE TABLE [HangFire].[JobQueue]
TRUNCATE TABLE [HangFire].[List]
TRUNCATE TABLE [HangFire].[State]
DELETE FROM [HangFire].[Job]
DBCC CHECKIDENT ('[HangFire].[Job]', reseed, 0)
UPDATE [HangFire].[Hash] SET Value = 1 WHERE Field = 'LastJobId'

This basically truncates all the tables and resets the seeding for the Job table (reseting job id's)

I think it's also worth mentioning that it is good and sensible practice to stop your application and make sure the worker processes have cleared up on your server before running any scripts


You can clear all hangfire jobs by Truncating all the hangfire tables and reset the seeding for the Job table. (Resetting job id's)

TRUNCATE TABLE [HangFire].[AggregatedCounter]
TRUNCATE TABLE [HangFire].[Counter]
TRUNCATE TABLE [HangFire].[JobParameter]
TRUNCATE TABLE [HangFire].[JobQueue]
TRUNCATE TABLE [HangFire].[List]
TRUNCATE TABLE [HangFire].[State]
DELETE FROM [HangFire].[Job]
DBCC CHECKIDENT ('[HangFire].[Job]', reseed, 0)
UPDATE [HangFire].[Hash] SET Value = 1 WHERE Field = 'LastJobId'

I found this solution on Hangfire Database Cleanup


I ended up dropping the tables, at first the query did not work at all, it just kept going and nothing happened. I then used TRUNCATE TABLE [HangFire].[State] and it all worked like a charm after. Here is the script I used for Hangfire 1.5.6 with UseSqlServerStorage:

GO
PRINT N'Dropping [HangFire].[FK_HangFire_State_Job]...';


GO
ALTER TABLE [HangFire].[State] DROP CONSTRAINT [FK_HangFire_State_Job];


GO
PRINT N'Dropping [HangFire].[FK_HangFire_JobParameter_Job]...';


GO
ALTER TABLE [HangFire].[JobParameter] DROP CONSTRAINT [FK_HangFire_JobParameter_Job];


GO
PRINT N'Dropping [HangFire].[Schema]...';


GO
DROP TABLE [HangFire].[Schema];


GO
PRINT N'Dropping [HangFire].[Job]...';


GO
DROP TABLE [HangFire].[Job];


GO
PRINT N'Dropping [HangFire].[State]...';


GO
DROP TABLE [HangFire].[State];


GO
PRINT N'Dropping [HangFire].[JobParameter]...';


GO
DROP TABLE [HangFire].[JobParameter];


GO
PRINT N'Dropping [HangFire].[JobQueue]...';


GO
DROP TABLE [HangFire].[JobQueue];


GO
PRINT N'Dropping [HangFire].[Server]...';


GO
DROP TABLE [HangFire].[Server];


GO
PRINT N'Dropping [HangFire].[List]...';


GO
DROP TABLE [HangFire].[List];


GO
PRINT N'Dropping [HangFire].[Set]...';


GO
DROP TABLE [HangFire].[Set];


GO
PRINT N'Dropping [HangFire].[Counter]...';


GO
DROP TABLE [HangFire].[Counter];


GO
PRINT N'Dropping [HangFire].[Hash]...';


GO
DROP TABLE [HangFire].[Hash];


GO
PRINT N'Dropping [HangFire].[AggregatedCounter]...';


GO
DROP TABLE [HangFire].[AggregatedCounter];


GO
PRINT N'Dropping [HangFire]...';


GO
DROP SCHEMA [HangFire];


GO
PRINT N'Update complete.';
