   Could you change the gRPC listening port of the liaison? The default port number will conflict with the data node. https://skywalking.apache.org/docs/skywalking-banyandb/latest/operation/configuration/#liaison--network

   Do you want to fix which one or some?
   1. self-obs bug
   2. expose `auto-compaction` for standalone mode
   3. change helm to support `auto-compaction` in cluster mode

   According to your liaison logs, you started up two data nodes: 192.168.1.85 and localhost.localdomain. I thought one of them was invalid.

   Do banyanDB and etcd support single node deployment? for example
   ./banyand data --etcd-endpoints= http://127.0.0.1:2379
   ./banyand liaison --etcd-endpoints= http://127.0.0.1:2379
   
   Does Banyandb 0.8.0 have any requirements for the ETCD version?

   Having a single node can be good, but it is not recommended due to the risk of a single point of failure.
   
   > Does Banyandb 0.8.0 have any requirements for the ETCD version?
   
   It should be >= 3.5

   I will investigate the issue. It appears that our use of etcd is causing the crash.

   It just started. As recommended, you are better to deploy etcd outside as a cluster, then this parameter has been exposed by etcd.

   After some investigation, I found that the etcd key space should be compacted periodically to free up space, as noted in https://etcd.io/docs/v3.5/op-guide/maintenance/#auto-compaction. 
   
   Currently, the standalone mode does not provide options for this setting. I plan to address this issue in milestone 0.9.0.
   
   I highly recommend using the cluster mode, where you can easily configure etcd settings.

   Liaison will accept the node with the role ["data"](https://github.com/apache/skywalking-banyandb/blob/main/api/proto/banyandb/database/v1/database.proto#L38) as its route table. You can check the contents of these nodes in etcd. There should be two nodes with the data role, and one of them has invalid content that you can remove manually.
