Can we know the endpoint types from service_id? such as it's from tidb, raw_kv client, cdc or others?

I don't think we can tell by service_id alone,
for example, both TiDB and raw_kv's gc_worker may use gc_worker as their service_id

So... Is it different in space_id? like cdc_xxx, tidb_xxx, client_xxxx . I would like to know who use the path.

currently, we use spaceID to differentiate key spaces, things like
default_rawkv, default_txnkv, default_tidb
serviceID is used to identify the specific service under that KeySpace, like
cdc, br, etc.
tidb cdc and rawkv cdc may have the same serviceID but different spaceIDs
rawkv cdc and rawkv br have the same spaceID but different serviceIDs
