**Is your feature request related to a problem? Please describe.**
There are many data of the same stock with different prices in the stock
price topic. I only need to keep the data of the latest price of the same
stock. How can I delete the historical price data of the same stock? Because
they take up too much storage space, I need to clean up the disk space.
**Describe the solution you'd like**
When topic compaction is enabled, you can configure whether to delete
duplicate data of the same key of this topic, so as to keep only the latest
data of the same key?
