The new version of client libraries (0.0.11) now supports the specification of arbitrary strings as types for realms. Although this has been possible in the public onedb API before, the RPC back-end could only request a limited number of realms, which has been fixed now.
In addition, the seed() operation has also been extended with an optional parameter specifying a seedType. This allows to potentially create seeds on different servers/cloud nodes.
The new maven dependencies is:
<dependency>
<groupId>one.client.jre</groupId>
<artifactId>oneClientJre.min</artifactId>
<version>0.0.11</version>
</dependency>
Alternatively, the standalone JAR can be obtained from the onedb website.
