# Create a namespace

# Create a namespace in Hermes {#ariaid-title1}

Organize your Kafka topics by creating a namespace.

## Vorbereitungen

Role required: hermes_admin or kafka_namespace_admin

## Warum und wann dieser Vorgang ausgeführt wird

Use namespaces to organize Kafka topics in logical ways. For example:

* Create namespace records for each Kafka cluster that replicates messages to Hermes.
* Create namespace records for each domain in a domain-separated instance. For more information, see [Hermes Messaging Service domain separation](https://servicenow-prod.fluidtopics.net/r1o7QfkLKdkll31xY_1NOA "Domain separation is supported for the Hermes Messaging Service. Domain separation enables you to separate data, processes, and administrative tasks into logical groupings called domains. You can control several aspects of this separation, including which users can see and access data.").
{#create-namespace-hermes__ul_upk_jsz_3zb}

## Prozedur

1. Navigate to AllHermes Messaging ServiceNamespaces.
2. Select New.
3. On the form, fill in the fields.  
   {#create-namespace-hermes__table_lds_3pz_3zb__entry__2}

   | Field | Description |
   |-|-|
   | Name | Name of the namespace. |
   | Topic Prefix | Prefix assigned to all topics in this namespace. Topics are assigned to namespaces based on the topic prefix. A scheduled job checks for new topics in Hermes. When it finds one, it creates a topic record and links the topic to the namespace. Warnung: To avoid conflicts between the app ID and the namespace that could result in unexpected behavior, don't specify a topic prefix beginning with `sn_` when creating a namespace record. |
   | Allowed Application Scopes | List of application scopes that have access to this namespace. |
   [Tabelle : 1. Kafka namespace form]

   {#create-namespace-hermes__table_lds_3pz_3zb}
4. Select Submit.

## Ergebnisse

A namespace record is created in the Kafka Namespace \[sys_kafka_namespace\] table. Topics created in or replicated to Hermes are assigned to the namespace based on the topic prefix.

## Nächste Maßnahme

* Organize topics yourself by creating one or more topic records and linking them to this namespace. See [Create a topic in Hermes](https://servicenow-prod.fluidtopics.net/txxCTguRtOzt1eWwv8k3Sg "Create a topic from within ServiceNow. Creating a topic from your instance adds a topic record to the Kafka Topics [sys_kafka_topic] table and adds a Kafka topic to Hermes.").
* Manage access to Kafka topics in the Hermes Kafka cluster by configuring Access Control Lists (ACLs) for this namespace in the certificate generator. See [Set up a secure connection to the Hermes Messaging Service](https://servicenow-prod.fluidtopics.net/E9eFecp0xYW~Av3YxMUT9w "Secure your Kafka topics by generating a ServiceNow instance-signed certificate.").
