It uses Python dataclasses to define table structures and generates CREATE, DROP, INSERT, MERGE, and DELETE SQL statements, then executes them asynchronously against database drivers like asyncpg or aiomysql. The library supports two main workflows: schema synchronization (comparing a source database state to a target Python dataclass definition and emitting transformation SQL) and data synchronization (inserting, upserting, or deleting rows from lists of tuples or dataclass instances).\n\nThe package is built around async/await patterns to maximize throughput when working with large datasets. It handles type mapping across SQL dialects, supports enumerations and composite types, and can generate SQL from dataclass definitions or discover existing database schemas via information_schema or pg_catalog. Runtime dependencies are minimal (json_strong_typing, truststore, typing_extensions), and the library targets modern Python versions (3.10+).","worth_installing":"Yes, if you need async bulk data loading or schema synchronization in Python. The library is actively maintained, has no known vulnerabilities, uses a permissive MIT license, and offers genuine performance advantages over traditional ORMs for insert/upsert workflows. Install friction is low. Not suitable if you require Python versions below 3.10 or prefer synchronous APIs."},"id":"pysqlsync","links":{"html":"https://skillfed.io/packages/pysqlsync","md":"https://skillfed.io/packages/pysqlsync.md","pypi":"https://pypi.org/project/pysqlsync/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-06","license_spdx":"MIT","license_treatment":"permissive","name":"pysqlsync","python_support":"supports_current","summary":"Synchronize schema and large volumes of data"},"popularity":{"monthly_downloads":107486,"position":12613,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.0.0"}
