shyjsarah opened a new pull request, #576: URL: https://github.com/apache/paimon-rust/pull/576
### Purpose Linked issue: close #575 `SHOW TABLES` should use catalog metadata without opening every listed table. The default DataFusion `SchemaProvider::table_type` implementation calls `table(name)`, which can initialize FileIO and turn a metadata-only operation into a table access. ### Brief change log - collect base-table and view types while listing catalog objects - override `PaimonSchemaProvider::table_type` to use the collected metadata instead of loading table providers - preserve temporary table/view precedence and catalog view classification - keep direct table reads on the existing lazy-loading path - add regression coverage for unavailable table loading and catalog view types ### Tests - `cargo fmt --all -- --check` - `cargo test -p paimon-datafusion --test sql_context_tests` - `cargo clippy -p paimon-datafusion --all-targets -- -D warnings` ### API and Format No public API or storage format changes. ### Documentation No documentation changes are required. -- This is an automated message from the Apache Git Service.
