Kripton 3.5.0 is released! There are some bug fixes and some new features that you can see in the release notes that I reported below. This version is all focused on ORM part of the library. Only two new major features are mentioned in this post. For other new features and bug fix, you can read release note, reported at the end of this post too.

Define a database in memory

Since this version is possible to create an SQLite database in memory simply using flaginMemory of annotation@BindDataSource. An example:

In this case, the data source version will be always 0, so migration task will not be executed.

Database migration task can be defined throws @BindDataSource

Another new feature is the capability to define migration task between database version throws @BindDataSource#updateTasks annotation attribute.

As reported in the above example code, a new annotation @BindDataSourceUpdateTask is introduced to accomplish this feature. Every task is defined to migration from version-1 to the version of the database (always step by 1). The version attribute specifies the destination version.

In the above example, to migrate data source from version 1 to 2, SampleUpdate02 task will be executed. To migrate data source from version 1 to 3, the executed task will be SampleUpdate02 and SampleUpdate03.
