: Avoid generic titles, like “Topics: incorrect layout of message sorting drop-down list”. Better use something like: “Topics: Message sorting drop-down list overlaps the "Submit" button”. --> **Describe the bug** (Actual behavior) There are 2 pages **Overview** and **Messages** where the number of a topic messages is shown. After the topic's compaction, the number of messages isn't updated/synced on **Overview** page. Please have a look at the screenshots below: **Expected behavior** Those metrics should be synced as soon as possible and show an up-to-date value. Otherwise, it's confusing 🤔 **Set up** **Steps to Reproduce** 1. Create a topic with **compact cleanup policy** 2. Produce some messages 3. Have a look at the number of messages there 4. Wait for topic compaction or trigger it manually 5. Have a look at the number of messages on **Overview** and **Messages** pages. The numbers are not equal. **Screenshots** **Additional context**

Direzione di ricerca: Investigate how the message count is computed on the Overview and Messages pages. Check the backend API endpoints (likely in the topic controller) to see if they return the same value. Review whether the Overview page uses a cached or aggregated metric that is not updated after compaction. Look at recent commits or PRs related to topic metrics. Examine the frontend data fetching logic for the Overview page to see if it re fetches after compaction events.
