## What it is
Yugong is a Java-based database migration and synchronization tool developed by Alibaba to move data from Oracle to MySQL/DRDS. It supports both full (bulk) and incremental (real-time) migration with data validation and cutover support.

## Use cases
- migrate oracle database to mysql
- oracle to mysql data migration tool
- sync data from oracle to mysql incrementally
- migrate oracle tables to alibaba drds
- full and incremental database migration
- validate data consistency during database migration
- switch production database from oracle to mysql with minimal downtime

## When to choose
- you need to migrate from Oracle to MySQL or DRDS with both bulk copy and ongoing incremental sync
- you want data validation and parallel replication during migration
- you prefer a pure-Java tool that runs on the JVM without extra infrastructure

## When to avoid
- you need migrations between database engines other than Oracle/MySQL/DRDS
- you want a modern actively developed tool with broad community support
- you need cloud-managed migration services with a GUI rather than a self-run Java application
