Assertion: amazon's source | /r/HasProperty | db instance
Facets:
Source sentences:
text: You can create multiple read replicas for a given source DB Instance and distribute your application
text: Automatic backups must be and remain enabled on the source DB Instance for read replica operations.
text: Typical reasons include: Write I/O volume to the source DB instance exceeds the rate at which changes can be applied to the read replica (this problem is particularly likely to arise if the compute capacity of a read replica is less than the source DB Instance)
text: If you desire to delete these DB Instances in addition to the original source DB Instance, you must explicitly do so using the DeleteDBInstance API or AWS Management Console.
text: You may use a read replica for disaster recovery of the source DB instance, either in the same AWS Region or in another Region.
text: The engine version (e.g., PostgreSQL 9.3.5) and storage allocation of a read replica is inherited from the source DB instance.
text: The I/O suspension typically lasts on the order of one minute, and is avoided if the source DB instance is a Multi-AZ deployment (in the case of Multi-AZ deployments, snapshots are taken from the standby).
text: Q: How many read replicas can I create for a given source DB instance?
text: Amazon RDS for MySQL, MariaDB, PostgreSQL, Oracle and SQL Server allow you to create up to 5 read replicas for a given source DB instance.
text: The amount of time between when data is written to the source DB instance and when it is available in the read replica will depend on the network latency between the two regions.
text: With Amazon RDS Read Replicas, which employ supported engines' native, asynchronous replication, database writes occur on a read replica after they have already occurred on the source DB instance, and this replication “lag” can vary significantly.
text: Examples might include adding a database index to a read replica that is used for business reporting, without adding the same index to the corresponding source DB instance.
text: Network partitions or latency between the source DB instance and a read replica Read Replicas are subject to the strengths and weaknesses of supported engines' native replication.
text: For Amazon RDS for PostgreSQL, you can use the pg_stat_replication view on the source DB instance to explore replication metrics.
text: If you desire to delete the Read Replica in addition to the source DB instance, you must explicitly do so using the DeleteDBInstance API or AWS Management Console.
