Changes

This pull request introduces a comprehensive migration from synchronous database session handling to asynchronous session handling across multiple modules in the aleph codebase. The changes aim to improve performance and scalability by leveraging asynchronous operations. The most important changes include replacing DbSessionFactory and DbSession with their asynchronous counterparts, updating session-related method calls to use async with, and modifying database operations to use await.

Migration to Asynchronous Database Sessions:

Core API Entrypoint Updates:

• Replaced make_engine and make_session_factory with make_async_engine and make_async_session_factory in src/aleph/api_entrypoint.py. Updated session initialization in configure_aiohttp_app to use asynchronous methods. [1] [2]

Chain-Specific Connector Updates:

• Migrated DbSessionFactory to AsyncDbSessionFactory in src/aleph/chains/bsc.py, src/aleph/chains/connector.py, src/aleph/chains/ethereum.py, and src/aleph/chains/nuls2.py. Updated constructors and session usage within these chain connectors to use asynchronous operations. [1] [2] [3] [4]

Chain Data Service Updates:

• Migrated DbSessionFactory and DbSession to AsyncDbSessionFactory and AsyncDbSession in src/aleph/chains/chain_data_service.py. Updated methods like add_pending_tx, add_and_publish_pending_tx, and others to use async with for session handling and added await for database operations. [1] [2] [3] [4]

Indexer Reader Updates:

• Migrated DbSessionFactory and DbSession to AsyncDbSessionFactory and AsyncDbSession in src/aleph/chains/indexer_reader.py. Updated methods such as fetch_range, fetch_new_events, and fetcher to use asynchronous session handling and database operations. [1] [2] [3] [4]

Additional Updates:

• Updated all database-related calls (e.g., commit, upsert, get_last_height) to use asynchronous versions with await. This ensures consistency and compatibility with the asynchronous session handling across the codebase.

How to test

This PR doesn't add any breaking change, it's just running things in Non I/O blockign way
