- Introduced `FilePathProvider` trait and its implementations (`WriteCachePathProvider`, `RegionFilePathFactory`) to manage SST and index file paths. - Updated `AccessLayer`, `WriteCache`, and `ParquetWriter` to use `FilePathProvider` for path management. - Modified `SstWriteRequest` and `SstUploadRequest` to use path providers instead of direct paths. - Files affected: `access_layer.rs`, `write_cache.rs`, `parquet.rs`, `writer.rs`. - **Enhanced Indexer Management**: - Replaced `IndexerBuilder` with `IndexerBuilderImpl` and made it async to support dynamic indexer creation. - Updated `ParquetWriter` to handle multiple indexers and file IDs. - Files affected: `index.rs`, `parquet.rs`, `writer.rs`. - **Removed Redundant File ID Handling**: - Removed `file_id` from `SstWriteRequest` and `CompactionOutput`. - Updated related logic to dynamically generate file IDs where necessary. - Files affected: `compaction.rs`, `flush.rs`, `picker.rs`, `twcs.rs`, `window.rs`. - **Test Adjustments**: - Updated tests to align with new path and indexer management. - Introduced `FixedPathProvider` and `NoopIndexBuilder` for testing purposes. - Files affected: `sst_util.rs`, `version_util.rs`, `parquet.rs`.
- Deleted the `enforce_max_output_size` function and related logic to simplify compaction input handling. - **Added Max File Size Option in `parquet.rs`:** - Introduced `max_file_size` in `WriteOptions` to control the maximum size of output files. - **Refactored Indexer Management in `parquet/writer.rs`:** - Changed `current_indexer` from an `Option` to a direct `Indexer` type. - Implemented `roll_to_next_file` to handle file transitions when exceeding `max_file_size`. - Simplified indexer initialization and management logic.

- Updated `ParquetWriter` in `writer.rs` to handle `current_indexer` as an `Option`, allowing for more flexible initialization and management. - Introduced `finish_current_file` method to encapsulate logic for completing and transitioning between SST files, improving code clarity and maintainability. - Enhanced error handling and logging with `debug` statements for better traceability during file operations.

changed the title
…Updated references and implementations in `access_layer.rs`, `write_cache.rs`, and related test files to use the new struct name. - **Add `max_file_size` support in compaction:** Introduced `max_file_size` option in `PickerOutput`, `SerializedPickerOutput`, and `WriteOptions` in `compactor.rs`, `picker.rs`, `twcs.rs`, and `window.rs`. - **Enhance Parquet writing logic:** Modified `parquet.rs` and `parquet/writer.rs` to support optional `max_file_size` and added a test case `test_write_multiple_files` to verify writing multiple files based on size constraints.
