High-performance IOPS rate is maintained throughout the lifetime of the database instance. The high-performance option can deliver up to 40000 IOPS per database instance. The general-purpose solution has a performance that delivers at 3 IOPS per provisioned GB that can scale up to 3000 IOPS. A high-performance choice for OLTP applications and another cost-effective solution for general-purpose use. There are two SSD backed options for storage in Amazon RDS. So, the performance of this database engine is considerably high, if you use the indexes and partitioning properly. No matter the size of the tables you have, the latency of DynamoDB is minimum, and it maintains within milliseconds. That can reduce the reading time from milliseconds to microseconds. In addition, the in-memory cache, DynamoDB Accelerator (DAX), can enhance the read performance by ten folds. There is less latency and response time when reading and writing data because of the high IO performance of SSDs. Performance of DynamoDB vs Amazon RDS DynamoDBĭynamoDB is known for high-performance as it can cope with more than 10 trillion requests within a single day with peaks greater than 20 million requests per second.
The significant difference between these two services is that Amazon RDS is relational, whereas DynamoDB is a NoSQL database engine. In addition, both of them are reliable and highly scalable with automated scalability and backup. Shared Attributes for DynamoDB and Amazon RDSĭynamoDB and Amazon RDS are both fully-managed by AWS, thus making the administration more manageable and allowing developers to focus more on using the database service. So, we can choose from six database engines, including Amazon Aurora, MySQL, and MariaDB. Unlike DynamoDB, RDS is the name of the service rather than the database engine itself. On the other hand, Amazon RDS stands for "Relational Database Service", and we mostly use it for structured and relational data (SQL). It is swift, reliable, and scalable, which makes working with NoSQL data much easier to handle. DynamoDB and Amazon RDS: An OverviewĭynamoDB is a database service for NoSQL data fully managed by Amazon Web Services. In this article, I will be discussing what these two services are and their similarities and differences. These two services are widely in use around the globe. Up to date stats improves Query performance.DynamoDB and Amazon RDS are two popular cloud-based database services managed and offered by Amazon Web Services (AWS). This is sort of a ledger about which data is stored in which node and which partition with in a node.

Redshift has "Analyze" operation that could be performed on tables, which will update the stats of the table in leader node.Redshift is forked out of PostgreSQL DB, and then AWS added "MPP" (Massively Parallel Processing) and "Column Oriented" concepts to it, to make it a powerful data store.It also has Composite Sort Keys and Interleaved Sort Keys, to support various use cases If you correctly define them on your tables along with above Distribution Keys, it further improves your Query performance. For instance, we can define Mapping/Meta-data tables with Distribution-All Key, so that it gets replicated across all the nodes, for fast joins and fast query results. If you correctly define them on your tables, it improves Query performance. Integration Platform as a Service (iPaaS).
