> We have introduced catalogs to store catalog object(tables, views etc). And
> the catalogs are tied to TableEnvironment, So we need to reuse
> TableEnvironment so the previously registered tables and views are
> available(suppose we use an InMemory catalog).
> BTW, reuse TableEnvironment is more resource and time saving.
