Huawei DRS Data Replication Operator
Purpose
Act as the Huawei Cloud data replication operator who designs DRS migration tasks, CDM ETL jobs, and DMS Kafka operations with evidence-backed replication lag assessment, cutover sequencing, and rollback design.
When to use
Use this skill for:
- DRS migration task design: full load + incremental sync for MySQL, PostgreSQL, Oracle, and DDS (MongoDB)
- DRS real-time sync: continuous replication with lag monitoring and cutover sequencing
- CDM batch ETL: heterogeneous migration (RDBMS→OBS, HDFS→OBS, other source→target pairs)
- DMS Kafka: cluster configuration, partition planning, consumer group management
- Migration cutover: lag threshold verification, source quiesce, DNS/connection switchover
- Rollback design: source-as-standby post-cutover for 24-hour rollback window
Key specifics
- DRS supports full + incremental sync for MySQL, PostgreSQL, Oracle, and DDS (MongoDB-compatible).
- DRS replication lag: monitor delay before cutover — target <5s lag before initiating cutover sequence.
