fix: conversion from TableMeta to TableMetaBuilder (#5693)

* refactor: use proc macro to generate conversion between TableMeta and TableMetaBuilder * chore: format * fix/partition-key-index: ### Update `TableMeta` and Add Partition and Alter Table Tests - **`metadata.rs`**: Modified `new_meta_builder` method in `TableMeta` to manually remove `value_indices` by setting it to `None` in the `TableMetaBuilder`. - **`partition_and_alter.result` & `partition_and_alter.sql`**: Added new test cases for creating, inserting, selecting, altering, and dropping a partitioned table `molestiAe`. These tests verify partitioning on the `sImiLiQUE` column and altering the table with a TTL setting. fix/partition-key-index: ### Remove Obsolete TODO Comment in `metadata.rs` - Removed an outdated TODO comment regarding the `new_meta_builder` function in `src/table/src/metadata.rs`. chore: check struct name in derive_meta_builder refactor: Simplify TableMeta struct name check in macro refactor: Improve ToMetaBuilder derive macro validation and error handling refactor: Enforce ToMetaBuilder macro for table::metadata::TableMeta struct * fix/partition-key-index: Update `partition_and_alter.sql` to modify TTL setting - Modified the TTL setting for the `molestiAe` table to '1d' in `partition_and_alter.sql`. * fix: sqlness * fix/partition-key-index: ### Update `TableMeta` and Test File Structure - **Enhancement**: Added a note in `metadata.rs` to always use `new_meta_builder` for creating `TableMetaBuilder`. - **Refactor**: Renamed test result and SQL files for better organization: - `partition_and_alter.result` to `alter/partition_and_alter.result` - `partition_and_alter.sql` to `alter/partition_and_alter.sql` * refactor: Simplify `derive_meta_builder` by initializing fields with `Default::default()` * fix/partition-key-index: ### Commit Summary - **Refactor `TableMetaBuilder` Initialization**: - Replaced `TableMetaBuilder::default()` with `TableMetaBuilder::empty()` across multiple files for initializing `TableMetaBuilder` instances. - Affected files include: - `src/catalog/src/system_schema.rs` - `src/common/meta/src/key/test_utils.rs` - `src/operator/src/req_convert/insert/fill_impure_default.rs` - `src/query/src/log_query/planner.rs` - `src/query/src/promql/planner.rs` - `src/query/src/range_select/plan_rewrite.rs` - `src/query/src/sql/show_create_table.rs` - `src/table/src/test_util/memtable.rs` - `src/table/src/test_util/table_info.rs` - **Enhance `TableMetaBuilder`**: - Added `custom_constructor` to `TableMeta` and implemented an `empty` method for `TableMetaBuilder`. - Modified `TableMetaBuilder` to include a `new_external_table` method with default values. - Updated `src/table/src/metadata.rs` to reflect these changes. - **Add Testing Feature**: - Introduced a conditional compilation for `test_util` in `src/table/src/lib.rs` to include testing utilities when the `testing` feature is enabled. - **Update `Cargo.toml`**: - Enabled the `testing` feature for the `table` module in `src/common/meta/Cargo.toml`. - **Modify `NumbersTable` Initialization**: - Replaced `TableMetaBuilder` with direct `TableMeta` struct initialization in `src/table/src/table/numbers.rs`. - **Test Result Update**: - Updated test results in `tests/cases/standalone/common/alter/partition_and_alter.result` to reflect changes in table meta handling. * fix: rename default to empty * docs: add doc for TableMetaBuilder::empty * chore: Update src/table/src/metadata.rs --------- Co-authored-by: Yingwen <realevenyag@gmail.com>
