![]() ![]() The rds querying is depended on the engine used and redshift uses Postgres standard. The administrative task in redshift which needs to be executed manually by the administrator of the cluster, that uses a delete marker for ‘DELETE’ and ‘UPDATE’ queries, it means the archival process is necessary for actual deletion and this process is to be done by using ‘VACUUM’ command, whereas, redshift also has an ‘ANALYZE’ command to ensure all metadata and tables are kept updated.īasically, the structure of the rds is row-oriented and it stores the data, on the other hand, redshift has a columnar structure so that it optimized fast retrieval of columns. The maintenance of rds is low than redshift because it has a simple architecture, also it has automated tasks so that it does not have more things to maintain by end-user. The performance of both the databases depends on the key distribution mechanism where the rds has sharding capability with carefully designed keys in which customers can get more performance, whereas the redshift has the option of SORT key and DIST key, when that is used correctly then the performance in joins and complex queries will improve, redshift is a fastest performing data warehouse on the computing platform. The resizing of instances can be done in few minutes because it supports elastic resize, the database unavailable time window is higher than that rds, it means seeing the storage capacity of scaling redshift is higher so that the unlimited number of users can access it. ![]() The scaling of rds is based on the virtual instances and that is done by reconfiguring the capability of virtual instances, the scaling of rds can take few minutes and it can be done in few clicks in the console of AWS, whereas the architecture of redshift is complex it means the scaling is not as seamless as it is in rds. When we have a choice to select different databases then the most important is to check the scalability of it, both rds and redshift allow us to scale the database as per the requirement. Key Differences of Amazon rds vs Redshift On the other hand, it has 16 terabytes per Amazon Redshift instance. Whereas, redshift computing resources include nodes with vCPU and 244 GN RAM. It has 64vCPU and 244GB RAM computing resources. Whereas the redshift uses adapted PostgreSQL as the database engine. Its database engine includes MySQL, SQL Server, Oracle database, Maria database, Amazon Aurora, and PostgreSQL. It is also flexible but it allows removing the cluster, creating a cluster, deleting the cluster, also to take a snapshot of it, and move that snapshot to a different region. It is flexible, hence we can able to scale the computing resources or we can scale the storage capacity which is associated with the database. On the other hand, we can create our own security groups and can attach to cluster, so that we can design our security parameters as per the requirements. It is secure so by using Amazon rds we can easily control the network for accessing our database, and also we get the option for isolating the database instances. Whereas, the costs of Redshift are also less to operate than any other cloud data warehouse. The cost of rds is less but we wanted to pay only for the resources which we would be consuming. Where its data volume is in petabytes, it has unlimited data storage. ![]() The data volume is in terabytes, and it has 64 terabytes storage limit. It works fine for OLTP (Online Transactional Processing) system which gives instant results with fewer data.Īnd, it works for OLAP (Online Analytical Processing) system, so that the analytical and reporting workload is heavy and it interferes with the OLTP database. Whereas, the Redshift is a non-relational database. Whereas, it is a petabyte-scale data warehouse service in the cloud. The Amazon rds is a web service in the cloud.
