If this is already explained clearly in the issue then this section is not needed. Explaining clearly why changes are proposed helps reviewers understand your changes and offer better suggestions for fixes. --> This makes it possible to support temporary views in datafusion-python without code duplication. Ref: apache/datafusion-python#1267 ## What changes are included in this PR? <!-- There is no need to duplicate the description in the issue here but it is sometimes worth providing a summary of the individual changes in this PR. --> - Add new public function `DataFrame::into_temporary_view` - Update `DataFrameTableProvider` with a new member that determines the `table_type` - Add a test ## Are these changes tested? <!-- We typically require tests for all PRs in order to: 1. Prevent the code from being accidentally broken by subsequent changes 2. Serve as another way to document the expected behavior of the code If tests are not included in your PR, please explain why (for example, are they covered by existing tests)? --> Yes, see added test `register_temporary_table` ## Are there any user-facing changes? <!-- If there are user-facing changes then we may require documentation to be updated before approving the PR. --> <!-- If there are any breaking changes to public APIs, please add the `api change` label. --> Yes, there is a new public function `DataFrame::into_temporary_view` --------- Co-authored-by: Andrew Lamb <andrew@nerdnetworks.org>
