MicroStream 5.0 has arrived… and, now, the Java persistence framework is open source.
MicroStream is a Java-native object graph persistence engine for storing any complex Java object graph or any single subgraph and restoring it in RAM at any time by using a new serialisation concept designed from scratch.
Classed as middleware, a persistence framework automates the storage of software application data into databases (it has particular use in relational databases) and works as an abstraction layer between the application itself and the database.
In working motion, a persistence framework is often responsible for bridging any conceptual differences that exist between an application and a database.
With MicroStream, not only the entire object graph, but also partial subgraphs, or only single objects can be restored in RAM on demand.
Beyond serialisation, the team at MicroStream confirms that it is ACID transaction safe, can handle class changes, provides a garbage collector for the storage, multi-threaded IO, and connectors for various data storages.
The technology itself launched in 2019 and is said to be similar to Java’s built-in serialisation, but more powerful.
According to MicroStream, this technology enables developers to process and store data with Java only.
With MicroStream, users do not need an object-relational-mapping framework anymore because this technology allows them to store any Java object graph natively.
There is no more expensive transformation to an incompatible data structure. This point is the key difference between MicroStream and all other persistence approaches on the market.
MicroStream has been used productively in business-critical projects for more than six years.
“It’s proven, stable and has a high code quality [so] now, it’s time to open source it. Open source provides strong value and great benefits for our community. The source code is now available for anyone to read. Debugging, finding and fixing bugs is possible. Security issues can be found and eliminated faster It gives you the flexibility to customise and extend MicroStream on your own,” notes the organisation, in a technical statement.
It is hoped that permanent reviews of the source code and numerous testing cycles by developers across the world will increase the stability of MicroStream.
