# Create a topic

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

* Release version: Australia

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.

## Before you begin

Role required: kafka_admin

## Procedure

1. Navigate to AllHermes Messaging ServiceTopics.
2. Select New.
3. On the form, fill in the fields.  
   {#create-topic-instance-hermes__table_iyn_bm2_3zb__entry__2}

   | Field | Description |
   |-|-|
   | Name | Name of the topic. The string that you enter is combined with the application ID and namespace to create the full Kafka topic name. Note: Don't include the `snc.<instance_name>` prefix with the topic name. |
   | Application ID | Application associated with the topic. Default is Stream Connect. |
   | Namespace | Namespace associated with the topic. You can either select a namespace created by the Kafka namespace administrator or select the Default Namespace if separate namespaces aren't configured for your instance. In ServiceNow, all Kafka topics link to a namespace. Namespaces are used to organize topics and, on a domain-separated instance, for domain separation. When a namespace is assigned to a particular domain, all the topics created in that namespace have the same domain. |
   | Partitions | Number of partitions to create for the topic. * Minimum value: 1 * Maximum value: 32 * Default value: 1 {#create-topic-instance-hermes__ul_znl_c1k_mxb} |
   | Active | Option to activate the topic. |
   [Table 1. Kafka Topic Form]

   {#create-topic-instance-hermes__table_iyn_bm2_3zb}
4. Select Submit.

## Result

The topic appears in both the Kafka Topics \[sys_kafka_topic\] table and in Hermes. If, for some reason, a topic can't be created in Hermes, it won't be created in the Kafka Topics \[sys_kafka_topic\] table either.
