> When I define catalog(schema) -> database(subschema) -> table three-level warehouse management mode, RootSchema is defined as Catalog, the example is as follows:
> - es
>     -- db1
>        --- table1
> - mysql
>     -- db2
>        --- table1
> When I use the !tables command under Sqlline, that will trigger the call
> getTableMap()
> RootSchema.getTableNames()
> RootSchema.getTable(String name)
> three methods,
> I extended RootSchema.getTableMap() and found that table1 with the same name will appear, then the !tables result set can only display one of the table items
> Can we consider getTableMap() to return Guava Multimap and similar data structures....
