Your application uses Cloud SQL for MySQL. Your users run reports on data that relies on near-real time, however, the additional analytics caused excessive load on the primary database. You created a read replica for the analytics workloads, but now your users are complaining about the lag in data changes and that their reports are still slow. You need to improve the report performance and shorten the lag in data replication without making changes to the current reports. Which two approaches should you implement? (Choose two.)

1. A. Create secondary indexes on the replica.
2. B. Create additional read replicas, and partition your analytics users to use different read replicas. — đáp án hiện tại
3. C. Disable replication on the read replica, and set the flag for parallel replication on the read replica. Re-enable replication and optimize performance by setting flags on the primary instance. — đáp án hiện tại
4. D. Disable replication on the primary instance, and set the flag for parallel replication on the primary instance. Re-enable replication and optimize performance by setting flags on the read replica.
5. E. Move your analytics workloads to BigQuery, and set up a streaming pipeline to move data and update BigQuery.
