> 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.
