HammerDB has featured a graphical transaction counter, this enables you to see the transaction rate taking place on the database during the test. Prior to v4.1 The transaction counter is designed not to be intrusive on the schema being tested. An example test script is shown including the transaction counter commands.

HammerDB Variable or Step Workloads are an advanced testing feature that enables you to automatically vary the load on the database over a period of time. When taking this approach you would not focus on the test result but instead monitor the databases ability to cope with the variation in demand and transaction response times.

In order to overcome these issues, the concept of paging and segmentation was introduced, where physical address space and virtual address space were designed. Here, virtual(logical) to physical address translation is much easier as segment tables store adequate information. A detailed description of these concepts is below.

However, as the two databases diverged from a shared common codebase, this presented a challenge in that it was not possible to modify the workload for MySQL or MariaDB without also changing the other.

Unfortunately, container security is much more difficult to achieve than security for more traditional compute platforms, such as virtual machines or bare metal hosts. However, to be secure, containers must be properly isolated from each other and from the host system itself. Harden the host operating system. Source code tests.

HammerDB is a load testing and benchmarking application for relational databases. All the databases that HammerDB tests implement a form of MVCC (multi-version concurrency control). On high-performance multi-core systems all the supported databases can return performance in the many millions of transactions per minute.

One of the most important concepts in analysing database performance is that of understanding scalability. When a system ‘scales’ it is able to deliver higher levels of performance proportional to the system resources available to it. In this example, we will compare MySQL 5.7.33 and MySQL 8.0.25 and MySQL 5.7.33.
