### Search before asking - [x] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar issues. ### Apache SkyWalking Component BanyanDB (apache/skywalking-banyandb) ### What happened Currently, the embedded etcd server in BanyanDB does not expose configuration options for `AutoCompactionMode` and `AutoCompactionRetention` through command-line flags or configuration files. These settings are critical for controlling the key space of etcd by managing how historical data (old revisions) is compacted. Exposing these parameters will allow users to customize the compaction behavior based on their workload and storage requirements. #### Background: - `AutoCompactionMode`: Determines the mode of automatic compaction (e.g., `periodic` or `revision`). - `AutoCompactionRetention`: Specifies the retention policy for old revisions (e.g., time duration for periodic mode or number of revisions for revision mode). Without the ability to configure these parameters, users have limited control over etcd's storage growth and may face issues with excessive disk usage or performance degradation due to unoptimized compaction settings. #### Proposal: Add command-line flags (or configuration options) to BanyanDB to allow users to set `AutoCompactionMode` and `AutoCompactionRetention` for the embedded etcd server. For example: - `--etcd-auto-compaction-mode`: To set the compaction mode (e.g., `periodic` or `revision`). default to `periodic` - `--etcd-auto-compaction-retention`: To set the retention value (e.g., `1h` for periodic mode or `1000` for revision mode). default to `1h` #### Example Usage: ```bash banyandb --etcd-auto-compaction-mode=periodic --etcd-auto-compaction-retention=1h ``` This would configure etcd to compact old revisions periodically, retaining data for the last 1 hour. ```bash banyandb --etcd-auto-compaction-mode=revision --etcd-auto-compaction-retention=1000 ``` This would configure etcd to compact based on revision numbers, retaining the last 1000 revisions. ### What you expected to happen Nan ### How to reproduce Nan ### Anything else _No response_ ### Are you willing to submit a pull request to fix 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.
