DatabaseMake sure to know and cover all services. 80% of the exam focuses on topics such as Aurora, RDS, DynamoDB, and DynamoDB.
AuroraUnderstand Aurora in depth
Know Aurora DR & HA by using Read Replicas anAurora promotes the use of read replicas according to the priority tier (tier 0 being the highest), and the largest size if the tier matches.
Aurora Global DatabaseAurora offers Global Database with cross-region read replicas for low latency readings. It is not multi-master and does not provide low latency write.
For primary read/write, know the Aurora Connection endpoints cluster
reader for read replicas
Custom for a particular group of cases
For a single instance, it is not recommended
Know Aurora Fast Failover techniquesset TCP keepalives low
Java DNS caching timeouts set to low
As low as possible, set the timeout variables in the JDBC connector string.
Use the provided read-and-write Aurora endpoints
Cluster cache management is required for Aurora PostgreSQL. Cluster cache management ensures that the application’s performance is maintained even if there is a failover.
Get Aurora Serverless
Aurora Backtrack features rewinds the DB cluster at the specified time. It is not meant to replace backups.
Server Auditing Events Supports Log in, DML and Permission Changes DCL. Schema changes DDL are also supported
The Aurora Cluster Cache management feature allows for fast failover
The Aurora Clone feature allows you to quickly and economically create clones
Aurora supports fault injection queries to simulate failovers such as node down, primary failover, and others.
RDS PostgreSQL or MySQL can be migrated into Aurora by creating an Aurora Read Replica. After the replica lag has zero, you can switch the DNS without data loss.
Supports Database Activity Streams for streaming audit logs to external services such as Kinesis
Supports stored procedures calling lambda function functions
DynamoDBUnderstand DynamoDB in depth
