ApsaraDB RDS for MySQLContent
Target customers: Users who use RDS instances and encounter the following scenarios: 1. The database system receives a small number of write requests but a large number of read requests, and a single primary RDS instance becomes overloaded by the read requests. 2. The primary RDS instance is temporarily unavailable due to backup or maintenance reasons, and you want to use read-only RDS instances of the primary RDS instance to process read requests to ensure business continuity. 3. You want to use read-only RDS instances to query and analyze large amounts of data without affecting the primary RDS instance. 4. If you use the read/write splitting feature, you want to use read-only RDS instances to prevent read/write lock contention and improve system performance and throughput. Features released: If your database system receives a small number of write requests but a large number of read requests, a single primary RDS instance may become overloaded by the read requests. This may interrupt your workloads. To offload read requests from the primary RDS instance, you can create one or more read-only RDS instances. Read-only RDS instances help increase the read capability of your database system and the throughput of your application. Examples: 1. If a single primary RDS instance is overloaded, you can create read-only RDS instances for the primary RDS instance to offload read requests from the primary RDS instance. 2. If the primary RDS instance in your database system is temporarily unavailable due to backup or maintenance reasons, you can use read-only RDS instances to process read requests. This helps ensure business continuity. 3. In scenarios such as report analysis, you can use read-only RDS instances to query and analyze a large amount of data. This does not affect the primary RDS instance. 4. If you enable the read/write splitting feature, you can use read-only RDS instances to prevent read/write lock contention and improve system performance and throughput.
