MidScale: MidPoint Scalability

Future scalability issues were foreseen in original midPoint design. MidPoint is not bound to any particular data store or database. Thanks to such foresight, midPoint has a flexible and replaceable data storage components. We would like to take advantage of this design feature and re-implement data storage components in a scalable way. Our plan is to redesign the database schema with scalability in mind. Also, we plan to take advantage of innovation in open source databases which was not readily available when midPoint development started almost a decade ago. Therefore we plan to fit our implementation specifically to PostgreSQL database to take full advantage of its capabilities.

We also plan to improve midPoint clustering mechanisms. Our goal is to support autoscaling capabilities used in cloud platforms, thus enhancing the on demand character of midPoint deployments. Higher scale also implies harder requirements on stability and robustness of the product. Therefore we plan to invest part of the effort to improve our quality assurance environment, especially focusing on scalability, performance and stability testing. MidPoint would greatly benefit from user experience improvements that can make administration of millions of identities easier.
