Managed Postgres and MySQL: protect the app, separate reporting
Fusion combines application databases with reporting on ClickHouse. Start with availability and recovery needs, then assess which analytical work should leave the primary.
Relevant capabilities
- Managed Postgres and MySQL
- High availability and point-in-time recovery
- ClickHouse reporting from Postgres, behind LakeGate
How should you compare the options?
- What recovery point and recovery time can the application tolerate?
- Which reporting queries affect production performance?
- Which extensions, versions and client behaviors are required?
What should you bring?
- Database version, size and extension inventory
- Application and reporting query samples
- Recovery objectives and maintenance windows
What does a practical first workflow look like?
- Check compatibility and define a reversible migration.
- Pilot the application path and Postgres reporting feed.
- Exercise recovery and switchover before moving production traffic.
What should you check before expanding?
- Check transaction and reporting consistency.
- Measure primary database load.
- Complete restore and failover exercises.
How should you evaluate the cost?
Compare the cloud bill, platform charges, operating effort and migration work for the same workload. Cloud capacity is not free. Charges and scope need agreement before paid deployment.
What needs checking before switching?
AWS and Google Cloud are available today; other deployment environments are roadmap. Preserve the existing workload and access path until compatibility, recovery and cutover checks pass.
