Edit the configuration settings for topics¶
View and edit the configuration settings for topics.
Important
Some topic configuration parameters are not configurable through this interface. These unmodifiable parameters
display a lock symbol (
) in the text entry box. They cannot be changed in either default or expert mode. See
Configurable topic parameters.
Edit basic topic settings¶
Select a cluster from the navigation bar.
Click the Topics cluster submenu. The All Topics page appears.
In the Topics table, click the ellipsis (
...) next to the topic name and choose Settings.
The Configuration page appears for the topic. Click Edit settings.
Tip
Click Show/Hide full config to toggle the view of all available configurations.
The basic configurations become available for editing. Only the most commonly modified settings are shown by default. Make any changes to the available fields. To edit additional settings in expert mode, see Edit topic settings in expert mode.
Tip
Click the information icon to view the tooltip for a setting.
Click Save changes.
Edit topic settings in expert mode¶
Caution
Be careful when setting configurations in expert mode. With expert mode, you have full control of every topic configuration and can potentially get your cluster into a bad state.
Follow the steps for Edit basic topic settings. On the basic configuration page, click Switch to export mode.
To leave expert mode without making any changes, click Leave expert mode.
Make your changes. Scroll down to the bottom of the page and click Save changes.
