Stock-level: return the status of the warehouse’s inventory: 4%.Order-status: retrieve the status of customers most recent order: 4%.Delivery: deliver orders asynchronously: 4%.

Payment: update the customer’s balance to record a payment: 43%. New-order: receive a new order from a customer: 45%. … the workload is defined by a mix of 5 transactions selected at random according to the balance of the percentage value shown as follows: Most “real” databases will have more tables than this, but it is a good starting point with enough variety to simulate real-world usage. This schema approximates a simple online transactional processing (OLTP) database. HammerDB provisions the following structured data schema in both PostgreSQL and MariaDB. #POSTGRESQL VS SQL DB SOFTWARE#
Now that we have the hardware and software deployed, we can give HammerDB the database credentials and issue a command to set up the test schemas.
No replication of any kind (no multi-AZ or horizontal partitioning). You can read more about TPC’s other measures on TPC’s official page. It implements a test called TPROC-C, which is loosely based on the TPC-C benchmark. HammerDB is a popular, open source database performance testing software. This service is a great way to get the most out of a database without being an expert on replication strategies, memory allocation/configuration, or other details required to maintain high availability, high performance, and data integrity.ĭeploying the databases in this way allowed me to compare their data access efficiency, with as little variance coming from configuration and hardware differences as possible. 
RDS is Amazon’s service for deploying managed relational databases. To compare the performance characteristics of these SQL databases, I deployed two AWS RDS instances, along with an EC2 instance running HammerDB.
PostgreSQL, MariaDB, and HammerDB deployment Let’s get right to the MariaDB vs PostgreSQL performance comparison.
Many new databases are compatible with PostgreSQL clients. MariaDB has to maintain some compatibility with MySQL. The reasons I would choose PostgreSQL over MariaDB for data storage include: However, in my opinion, PostgreSQL is better than MariaDB, and you should use it unless you have a specific use case that requires MariaDB. Both systems will work well as a general-purpose RDBMS. PostgreSQL and MariaDB are great open source databases.
