# **Jobber**
------------------------------
Jobber is lightweight, simple and distributed task scheduler.
[](https://badge.fury.io/nu/Jobber)
### NuGet Packages
```
PM> Install-Package Jobber
```
###Features:
- Easy to use
- Pub/Sub mode distributed task scheduling
- Standalone mode task scheduling
- Includes high availability modes for producers (ActiveActive-ActivePassive)
- Includes service recovery modes
- Logging (currently only support NLog)
###To-Do:
- Dashboard for service instances
- Abstraction for logging
Usage:
-----
For **standalone** job worker mode:
```cs
class TodoStandaloneJobWorker : StandaloneJobWorkerBase
{
protected override void ExecuteJob()
{
Console.WriteLine("Hello World!");
}
}
```
just inherit the _StandaloneJobWorkerBase_ for your job worker class, and then initialize as follows:
```cs
class Program
{
static void Main(string[] args)
{
string jobName = "Todo";
int restartDelayInMinutes = 1;
TimeSpan schedulingTickTime = TimeSpan.FromSeconds(5);
TimeSpan lockDuration = TimeSpan.FromSeconds(10);
List redisEndPoints = new List()
{
new DnsEndPoint("", 6379)
};
JobberBuilder.Instance.SetJobName(jobName)
.EnableServiceRecovery(restartDelayInMinutes)
.CreateStandaloneJobWorker()
.SetStandaloneJobWorker()
.SetSchedulingTickTime(schedulingTickTime)
.HighAvailabilitySetup()
.UseActivePassive()
.InitializeRedisForLocking(redisEndPoints)
.SetLockingDuration(lockDuration)
.Then()
.RunAsLocalService();
}
}
```
For **pub/sub** job worker mode, firstly let's initialize job producer.
```cs
class TodoJobProducer : JobProducerBase
{
protected override List> GetJobs()
{
List> jobs = new List>
{
new TodoJob
{
Data = new Todo() {TodoId = 1, TodoNumber = Guid.NewGuid().ToString()}
},
new TodoJob
{
Data = new Todo() {TodoId = 2, TodoNumber = Guid.NewGuid().ToString()}
}
};
return jobs;
}
}
```
just inherit the _JobProducerBase_. TJob is your job entity. After this, override the _GetJobs()_ method and return your job data. Now initialize producer as follows:
```cs
class Program
{
static void Main(string[] args)
{
string jobName = "Todo";
string rabbitMqUri = "";
string rabbitMqUserName = "";
string rabbitMqPassword = "";
string rabbitMqTodoQueueName = "todo.queue";
int restartDelayInMinutes = 1;
TimeSpan schedulingTickTime = TimeSpan.FromSeconds(5);
TimeSpan lockDuration = TimeSpan.FromSeconds(10);
List redisEndPoints = new List()
{
new DnsEndPoint("", 6379)
};
JobberBuilder.Instance.SetJobName(jobName)
.EnableServiceRecovery(restartDelayInMinutes)
.CreateJobProducer()
.SetRabbitMqCredentials(rabbitMqUri, rabbitMqUserName, rabbitMqPassword)
.SetQueueName(rabbitMqTodoQueueName)
.SetJobProducer()
.SetSchedulingTickTime(schedulingTickTime)
.HighAvailabilitySetup()
.UseActivePassive()
.InitializeRedisForLocking(redisEndPoints)
.SetLockingDuration(lockDuration)
.Then()
.RunAsLocalService();
}
}
```
For job consumer:
```cs
class TodoJobConsumer : JobConsumerBase
{
public override async Task ConsumeJob(ConsumeContext> job)
{
await Console.Out.WriteLineAsync(job.Message.Data.TodoNumber);
}
}
```
then initialize job consumer as follow:
```cs
class Program
{
static void Main(string[] args)
{
string jobName = "Todo";
string rabbitMqUri = "";
string rabbitMqUserName = "";
string rabbitMqPassword = "";
string rabbitMqTodoQueueName = "todo.queue";
int incrementalRetryLimit = 3;
TimeSpan initialIncrementalRetryInterval = TimeSpan.FromMinutes(5);
TimeSpan intervalIncrementalRetryIncrement = TimeSpan.FromMinutes(10);
int restartDelayInMinutes = 1;
JobberBuilder.Instance.SetJobName(jobName)
.EnableServiceRecovery(restartDelayInMinutes)
.CreateJobConsumer()
.SetRabbitMqCredentials(rabbitMqUri, rabbitMqUserName, rabbitMqPassword)
.UseIncrementalRetryPolicy(incrementalRetryLimit, initialIncrementalRetryInterval, intervalIncrementalRetryIncrement)
.SetQueueName(rabbitMqTodoQueueName)
.SetJobConsumer()
.RunAsLocalService();
}
}
```
