> Currently, inline tables such as {{fromDataStream}} or {{from(TableDescriptor)}} as well as {{toChangelogStream}} or {{Table.executeInsert(TableDescriptor)}} create an artifical temporary table with object identifier.
> This is due to Calcite that forces {{RelBuilder.scan}} to have an object identifier.
> Instead we should:
> - Create an internal {{RelOptTable}} that wraps {{CatalogTable}}
> - Various flavors of {{CatalogTable}} can store the {{DataStream}} object or information of the {{TableDescriptor.}}
> - Manually create {{LogicalTableScan}}
