Eclipse store (microstream) support

Hi all,
In a recent infoq article in Jakarta EE data specification, an example of using it with jnosql along with eclipse store. 
Eclipse store is not listed in jnosql supported databases page.
I was wondering where I can get more info on how to use the 2 techs together.
I am currently porting my jpa app to eclipse store and I am interested to keep things a spec aligned as possible...
Thanks
