Schema Migration Python Packages

clickhouse-migrations

SQL-file schema migrations for ClickHouse: cluster-aware, both drivers, schema dump & diff, opt-in Keeper lock, offline validate + pre-commit hook. CLI, Python API, GitHub Action, Docker.

graflo

Describe a labeled property graph once in a YAML manifest; GraFlo builds the schema and ingests records from CSV, JSON, Parquet, SQL, RDF/SPARQL, REST APIs or Kafka into ArangoDB, Neo4j, TigerGraph, FalkorDB, Memgraph, NebulaGraph, PostgreSQL or a directory on disk.

dbt-plan

dbwarden

DBWarden is a database migration system for Python/SQLAlchemy projects

smart-data-engine-sdk
