Database Ranking

Motivation
“Data is the new Oil”. Data and data processing is one of the central IT topics of the 2020s. Applications in the areas of IoT, Industry 4.0, machine learning, AI, eCommerce, social media, etc. generate and process huge amounts of data.
For this reason, there are now over 600 different database management systems with a wide variety of data structures and operating modes. Each database management system has its individual specialization and suitability here.
It is not about which database is the best or the most popular. It is about which database can provide the best performance in which scenario.
Decisions should not be made solely on the basis of popularity, features and (especially not) data structures, but above all by including reliable data on performance and scalability.
Database performance problems, inefficient solutions and over-sized computing power (“Kill it with iron!”) must be a thing of the past. In the future, IT applications must be properly scaled and equipped with the best possible technology in order to be efficient and competitive.
This database ranking serves as a first orientation!
We decided to make this data publicly to rise the awareness of the performance topic, starting discussions and making better decisions in the FUTURE!

Call for Participation
The future size and content of the database ranking, i.e. the number of databases and workloads available, depends heavily on the dissemination and feedback from the IT community.
- Please comment on the results.
- Please share the ranking with your colleagues.
- Please link the ranking in your posts, tweets, blog articles.
- Please reach out to database vendors and ask them to participate.
And if you are interested in actively participating and descending into the world of performance engineering, please contact us!
Workloads
A central concept of the ranking is the focus on a wide variety of workloads that IT applications, their users or their components generate and that the database has to deal with.
In general, the following workload types are distinguished:
- CRUD: Simple READ, WRITE, UPDATE and DELETE operations
- OLTP: Transactional, complex operations of data processing
- OLAP: Analytical batch processes
- HTAP: Hybrid transactional and analytics processing
- Time-Series: Time-series data with very simple, but high-frequency access patterns
In addition to the access pattern, other workload characteristics can have a major impact
- Distribution of read/write/… operations
- Number of parallel accesses
- Access pattern and caching
- Size of the data sets
- Total number of data sets
The load is generated using publicly available benchmark suites such as the Yahoo! Cloud Serving Benchmark Suite (YCSB).
Currently, we have defined and integrated the following workloads:
- CRUD: General Purpose (at 5 different scaling sizes) based on the YCSB.
The exact specifications can be found below the ranking in detail.
Databases
The following DBMS and DBaaS offerings are currently (see status) included (categorized and sorted alphabetically):
SQL
- AWS RDS for PostgreSQL (DBaaS)
- Azure Database for PostgreSQL (DBaaS)
- Oracle MySQL (community)
- PostgreSQL (open-source)
NoSQL
- Apache Cassandra (open source)
- Couchbase (community)
- MongoDB (community)

Cloud
Database Performance KPIs may vary on different cloud systems. Please refer to the literature attached below. Therefore, measurements are performed on multiple cloud providers.
The following cloud providers are currently included:
How it Works
The database benchmark measurements are performed using a science-based methodology and automated benchmarking technology.
For all measurements the Benchmarking-as-a-Service platform of benchANT is used. This is the technical product of Dr. Daniel Seybold and Dr. Jörg Domaschka and is based on more than 7 years of scientific research, as well as 2 years of industrial use.
Procedure of the benchmarking
The benchmarking platform of benchANT enables automated performance and scalability benchmarks of databases on cloud resources. Hereby, automatically
- allocates the cloud resources for the database instances
- the databases are installed and configured
- a separate cloud resource is allocated for workload execution
- load phase for initial test phase
- run phase with defined workload
- collection of measurement results
- testing of the measurement results
- preparation of the measurement results
- release of the cloud resources
This process takes 20-300 minutes depending on the size of the workload and can be performed multiple times per configuration for statistically provable results.
Scientific Literature
The scientific basis of the benchmarking method as well as many of the statements made above are based on findings from over 7 years of research.

Adding more …
… more databases/workloads/cloud
The goal is to measure and publish as many databases and clouds as possible for different workloads.
