Topics

The Topics page lists the cluster’s topics with a name filter, and a Hide System Topics toggle to keep the internal _-prefixed topics out of the way. Click a topic to open its detail page; click Create Topic to add one.

Creating a topic

The create form slides in as a resizable drawer — the table stays usable behind it:

1. Enter a Topic name (letters, digits, -, _, .), and adjust the number of partitions and replication factor if the defaults aren’t right.
2. (Optional) expand Configs. The common creation-time decisions are labelled fields — Cleanup policy (delete / compact / compact,delete), Retention time, Retention size, Max message size. For anything else, Add config offers every broker config by name, with Kafka’s official description on hover. Whatever you skip gets the broker default.
3. Submit — the table filters to the new topic, and the success notification offers a View topic? shortcut to its details.

The topic detail page

Four tabs, plus header actions (Refresh, Produce Message):

• Messages — browse or live-tail the topic’s records; covered in depth in the Messages guide.
• Partitions — one row per partition: leader broker, replicas, in-sync replicas, offsets — and the on-disk size when log-dir describing is enabled.
• Configuration — the topic’s effective configuration, searchable and sortable. The Delete Topic action lives here too.
• Schema — the key and value schemas registered for this topic under the standard topic-name convention (<topic>-key / <topic>-value). If none is registered yet, the card offers a Create Schema shortcut that pre-fills the create form for this topic.
