Implement compressed and uncompressed transaction storage with SQL streaming parser #55
Conversation
…reaming parser - Added `CompressedStorage` for handling `.sql.gz` files with sync points for efficient seeking. - Introduced `UncompressedStorage` for plain `.sql` files without compression. - Created `SqlStreamParser` for streaming SQL statement parsing, supporting various quote types and comments. - Developed `TransactionStorage` trait to abstract storage operations, enabling seamless switching between compressed and uncompressed implementations. - Implemented a `StorageFactory` to create storage instances based on environment configuration. - Added comprehensive tests for both storage implementations and the SQL parser to ensure functionality and correctness.

Code Review
This pull request introduces a significant and valuable feature: a storage abstraction for handling both compressed and uncompressed transaction files, complete with a streaming SQL parser. This is a great step towards improving storage efficiency and handling large transactions. The use of a TransactionStorage trait and a StorageFactory provides a clean and extensible design.
My review focuses on a few areas to further enhance the implementation, particularly around ensuring all I/O operations are non-blocking, improving the memory efficiency of the compression workflow, and increasing the robustness of the new SQL parser. The feedback provided aims to align the implementation more closely with the performance and efficiency goals of the pull request.

Code Review
This pull request introduces compressed and uncompressed transaction storage, a streaming SQL parser, and a storage factory for efficient CDC data handling. The changes include new modules for compressed and uncompressed storage, updates to dependencies, and modifications to the transaction manager to support the new storage abstraction. The code has been reviewed, and several suggestions have been made to improve code clarity, error handling, and adherence to best practices.

Instead of parsing the SQL from the uncompressed file again, consider passing the statements vector directly to the write_transaction function. This avoids redundant parsing and improves efficiency.
