Migration from a Database
Process
Elasticsearch supports full-text search and ad hoc queries. It is often used as a supplement to relational databases, such as GaussDB(for MySQL), to improve the full-text search and high-concurrency ad hoc query capabilities of databases.
The following figure shows the process of migrating data from a database.
This migration solution is convenient and flexible.
- Convenient: You can start a cutover while the CSS synchronizes incremental data.
- Flexible: Data can be added, deleted, modified, and queried on both sides.
Migration Guide
Data Replication Service (DRS) can be used to migrate and synchronize data between relational databases, such as GaussDB(for MySQL). For details about the supported database types, see Synchronization Overview.
