Hangfire.MySql.Core is based on Hangfire.MySqlStorage(https://github.com/arnoldasgudas/Hangfire.MySqlStorage)
I fix some bug and support .net standard 2.0
MySql storage implementation of Hangfire - fire-and-forget, delayed and recurring tasks runner for .NET. Scalable and reliable background job runner. Supports multiple servers, CPU and I/O intensive, long-running and short-running jobs.
Now, support table prefix
services.AddHangfire(x => x.UseStorage(new MySqlStorage(Configuration.GetConnectionString("Hangfire"),new MySqlStorageOptions(){TablePrefix = "Custom"})));
Install MySQL
Run the following command in the NuGet Package Manager console to install Hangfire.MySql.Core:
Install-Package Hangfire.MySql.Core
Use one the following ways to initialize MySqlStorage
:
- Create new instance of
MySqlStorage
with connection string constructor parameter and pass it toConfiguration
withUseStorage
method:
GlobalConfiguration.Configuration.UseStorage(
new MySqlStorage(connectionString));
- There must be
Allow User Variables
set totrue
in the connection string. For example:server=127.0.0.1;uid=root;pwd=root;database={0};Allow User Variables=True
- Alternatively one or more options can be passed as a parameter to
MySqlStorage
:
GlobalConfiguration.Configuration.UseStorage(
new MySqlStorage(
connectionString,
new MySqlStorageOptions
{
TransactionIsolationLevel = IsolationLevel.ReadCommitted,
QueuePollInterval = TimeSpan.FromSeconds(15),
JobExpirationCheckInterval = TimeSpan.FromHours(1),
CountersAggregateInterval = TimeSpan.FromMinutes(5),
PrepareSchemaIfNecessary = true,
DashboardJobListLimit = 50000,
TransactionTimeout = TimeSpan.FromMinutes(1),
TablePrefix = "Hangfire"
}));
Description of optional parameters:
TransactionIsolationLevel
- transaction isolation level. Default is read committed.QueuePollInterval
- job queue polling interval. Default is 15 seconds.JobExpirationCheckInterval
- job expiration check interval (manages expired records). Default is 1 hour.CountersAggregateInterval
- interval to aggregate counter. Default is 5 minutes.PrepareSchemaIfNecessary
- if set totrue
, it creates database tables. Default istrue
.DashboardJobListLimit
- dashboard job list limit. Default is 50000.TransactionTimeout
- transaction timeout. Default is 1 minute.
Number of opened connections depends on Hangfire worker count. You can limit worker count by setting WorkerCount
property value in BackgroundJobServerOptions
:
app.UseHangfireServer(
new BackgroundJobServerOptions
{
WorkerCount = 1
});

Please use Visual Studio or any other tool of your choice to build the solution
In order to run unit tests and integrational tests set the following variables in you system environment variables (restart of Visual Studio is required):
Hangfire_SqlServer_ConnectionStringTemplate
(default: server=127.0.0.1;uid=root;pwd=root;database={0};Allow User Variables=True
)
Hangfire_SqlServer_DatabaseName
(default: Hangfire.MySql.Tests
)
