Hi Jingsong, thanks.
The implementation of these statements in TableEnvironmentImpl is called
through the catalog api.
but it does support some new override methods on the catalog api side, and
I will update it later. Thank you.
e.g.
TableEnvironmentImpl
@Override
public String[] listDatabases() {
return catalogManager
.getCatalog(catalogManager.getCurrentCatalog())
.get()
.listDatabases()
.toArray(new String[0]);
}
Best Regards,
Ran Tao
