# Topics

> Browse, create, configure, and inspect topics — partitions, configuration, and per-topic schemas.

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](/guides/messages).
* **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](/guides/schema-registry#registering-a-schema)
  for this topic.

<Note>
  Deleting a topic deletes its records — it's the one genuinely destructive
  action in this area, and it lives behind a confirmation modal on the
  Configuration tab.
