What is AmazonRDS?

Amazon Relational Database Service (RDS)

Database engine employed by RDS

  • PostgreSQL
  • MariaDB
  • Amazon Aurora
  • MySQL
  • Oracle
  • SQLServer



RDS cannot use MyISAM as a storage engine for MySQL. In MySQL, the recommended storage engine is InnoDB.

The other options are best practices and recommended in the AWS MySQL RDS documentation.

lead replica

Old data may be displayed by replication Lag


Because the read replica is a separate database instance that is replicated asynchronously, replicated data is susceptible to lag and may not display some of the most recent transactions. This is called replication lag.


High-speed reads using up to 5 read replicas




Database encryption can be performed during database creation.


To encrypt Amazon RDS DB instances and snapshots during storage, enable the encryption option for Amazon RDS DB instances. Data to be encrypted during storage includes basic storage of DB instances, automatic backups, read replicas, and snapshots.
