Hi, may I ask the scenario? Unified connector is more like a middle stage in migrating from hive to iceberg/hudi.., cause iceberg/hudi are common upgrade methods for hive, users don't need to care about which catalog they are using. or in some companies, for example, there are both iceberg and hudi, although this is not common to see, they can use a unified connector to unify user experience. but for Kudu I think is a different scenario
Of course, in our scenario, the metadata of hive
/iceberg
/kudu
is stored in hms. When users use Trino
, they don't need to worry about what type of table they are accessing, they can use hive
uniformly for access. The engine can automatically route to the correct catalog, just like the purpose of unified catalog
. Therefore, I believe that as long as the storage of metadata is the same, it can be accessed through a catalog, which can greatly simplify user usage.

you mean the table redirection feature in trino? that also works between hive connector and kudu connector when it comes to hms?

Yes, the community supports the redirect of hive to iceberg, and we have extended the redirect of hive to kudu ourselves
