Query Optimization
This is an article by Oliver Krohne published in Videscope Magazin #002. Oliver works as an Engineer in R&D (Scale Group) at Versant. Prior to to his work with Versant, he wrote his diploma thesis about query performance and optimization.
Users of the Versant Object Database come from very different industries. Whether in bioinformatics, telecommunications or online gaming – they all have one thing in common. Their great demands on performance.
To meet those demands, we have carried out extensive studies and tests in the Versant Lab on the question of how we can optimize queries. The true power of a database is demonstrated in its handling of queries. How quickly can we generate the results for a given query? And how can we reduce expenditures in terms of memory usage, disk access and communication? The following text outlines the basic challenges and findings.
Performance Boost for Latches
The Service Release 4 of the Versant Object Database 7.0.1. has been launched with a multitude of enhancements for improved performance and scalability.Among other, we have introduced dramatic latch performance improvements. Now, Lab tests with real-life customer applications have shown dramatic performance improvements.
Object Model Design
FastObjects gives you complete freedom in designing your object model. Nevertheless – with regard to performance – you should consider some things when creating your object model. The proposals presented in this article are by no means to be interpreted as limitations to your freedom to design your object model to fit your needs. But when performance is essential, you should be aware of the following in your object model design in order to help FastObjects run at its optimum.
Use a Minimum Number of Classes in Your Object Model
One thing you should consider during the design phase is the granularity of your object model. For every object in the database FastObjects has to perform certain maintenance tasks. For example, each object gets its own object identity. And, by default, a special collection type to hold all objects of a specific class, called an extent, is maintained. Also, relationships among objects must be maintained, etc.
