hanahmily opened a new issue, #11987: URL: https://github.com/apache/skywalking/issues/11987
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar feature requirement. ### Description I suggest adding a new feature to BanyanDB that supports TTL (Time to Live) for tags and fields. This feature would enable BanyanDB to automatically remove specific tag or field data based on the TTL rules defined on a Group. Currently, BanyanDB only supports TTL for the entire Group, which means that data can accumulate indefinitely, potentially causing storage issues. By implementing TTL for tags and fields, only relevant and recent data will be stored, which optimizes storage usage. Furthermore, the proposed [hot-warm-cold architecture](#11945) could be utilized to set different TTL for cold, warm, or hot data, respectively. ### Use case _No response_ ### Related issues _No response_ ### Are you willing to submit a pull request to implement this on your own? - [ ] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
