Hangfire.Couchbase

Official Site Latest version Build status

This repo will add a Couchbase N1QL storage support to 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.

Installation

Hangfire.Couchbase is available as a NuGet package. Install it using the NuGet Package Console window:

PM> Install-Package Hangfire.Couchbase

Usage

1. Using the ClientConfiguration to initialize the server
ClientConfiguration configuration = new ClientConfiguration {
    BucketConfigs = new Dictionary<string, BucketConfiguration> {
      {"default", new BucketConfiguration {
          PoolConfiguration = new PoolConfiguration {
              MaxSize = 6,
              MinSize = 4,
              SendTimeout = 12000
          },
          DefaultOperationLifespan = 123,
          Password = "password",
          Username = "username",
          BucketName = "default"
      }}
    }
};

GlobalConfiguration.Configuration.UseCouchbaseStorage(configuration, "<defaultBucket>");

If you're using Couchbase 5.0+, then you'll need to supply RBAC credentials:

ClientConfiguration configuration = new ClientConfiguration {
   BucketConfigs = new Dictionary<string, BucketConfiguration> {
     {"default", new BucketConfiguration {
         PoolConfiguration = new PoolConfiguration {
             MaxSize = 6,
             MinSize = 4,
             SendTimeout = 12000
         },
         DefaultOperationLifespan = 123,
         BucketName = "default"
     }}
   }
};
configuration.SetAuthenticator(new PasswordAuthenticator("<username>", "<password>"));
GlobalConfiguration.Configuration.UseCouchbaseStorage(configuration, "<defaultBucket>");
2. Using the XML configuration to intialzie .Net application
<configSections>
  <sectionGroup name="couchbaseClients">
    <section name="couchbase" type="Couchbase.Configuration.Client.Providers.CouchbaseClientSection, Couchbase.NetClient" />
  </sectionGroup>
</configSections>
<couchbaseClients>
  <couchbase>
    <servers>
      <add uri="http://localhost:8091"></add>
    </servers>
    <buckets>
      <add name="default" password="password" />
    </buckets>
    <serializer name="CustomSerializer" type="Hangfire.Couchbase.Json.DocumentDefaultSerializer, Hangfire.Couchbase" />
  </couchbase>
</couchbaseClients>
GlobalConfiguration.Configuration.UseCouchbaseStorage("couchbaseClients/couchbase", "<defaultBucket>");
3. Using the JSON configuration for .Net Core application
{
  "couchbase": {
    "basic": {
      "servers": [
        "http://localhost:8091/"
      ],
      "buckets": [
        {
          "name": "default",
          "password": "password"
        }
      ],
      "serializer": "Hangfire.Couchbase.Json.DocumentDefaultSerializer, Hangfire.Couchbase"
    }
  }
}
IConfigurationBuilder builder = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

IConfigurationRoot configuration = builder.Build();
GlobalConfiguration.Configuration.UseCouchbaseStorage(configuration, "couchbase:basic", "<defaultBucket>");

You can also customize some of the options to fine tune the job server. The below are defaults; if no overrides found

Hangfire.Couchbase.CouchbaseStorageOptions options = new Hangfire.Couchbase.CouchbaseStorageOptions
{
    RequestTimeout = TimeSpan.FromSeconds(30),
    ExpirationCheckInterval = TimeSpan.FromSeconds(30),
    CountersAggregateInterval = TimeSpan.FromMinutes(1),
    QueuePollInterval = TimeSpan.FromSeconds(2)
};

GlobalConfiguration.Configuration.UseCouchbaseStorage(configuration, "<defaultBucket>", options);
